Looking for applications of BDDs to problems involving x,y concept - linear-programming
I am looking at the applications of BDD to figure out if it's possible to implement the x,y concept there.
Let me explain.
Let's say I have z of something to distribute in an x,y coordinate plane. The constraints are:
All the z items have to be placed in the x,y coordinate plane.
Some of the z items have to be a certain distance away from each other.
I think integer linear programming can sort this out. For example, with a set of equations, I can represent the constraints above and do linear programming to solve for the exact locations.
But what I am asking is if BDD can help with this?
In other words, can Binary Decision Diagram represent x,y coordinates and can I represent the above constraints with Boolean functions (equivalent to the set of equations above) and BDDs be manipulated to sort out the above constraints for exact locations just like linear programming?
I do not have any concrete examples to show but I think representing x,y coordinates equivalent in Binary is a place to start?
Yes, it is possible to encode the given integer-valued problem of placement over a plane using binary decision diagrams, and thus compute answers (as satisfying assignments). For example, using the Python package omega (which uses the Python package dd for BDD computations):
from omega.symbolic import fol
fol = _fol.Context()
# Register integer-valued variables, with ranges of representation using BDDs
fol.declare(x1=(0, 11), y1=(0, 11), x2=(0, 11), y2=(0, 11))
# Encode the problem:
#
# Two points on a Euclidean plane are represented by their Cartesian coordinates
# `x1, y1` and `x2, y2`.
# Each point is in the square mesh `x \in 1..10 /\ y \in 1..10`.
#
# Note that the variables are declared with larger domains,
# in order to ensure that this boundary constraint is representable with the
# resulting BDDs.
#
# The distance between the two points should be the square root of 10.
expr = r'''
(x1 >= 1) /\ (x1 <= 10)
/\ (x2 >= 1) /\ (x2 <= 10)
/\ (y1 >= 1) /\ (y1 <= 10)
/\ (y2 >= 1) /\ (y1 <= 10)
/\ (x1 - x2) * (x1 - x2) + (y1 - y2) * (y1 - y2) = 10
'''
# Solve the problem, by adding creating a BDD for it
u = fol.add_expr(expr)
# Enumerate all solutions (i.e., all satisfying assignments)
# These are all the pairs of points within the box mesh x \in 1..10 /\ y \in 1..10
# that have a distance equal to the square root of 10.
assignments = list(fol.pick_iter(u))
print(assignments)
Using BDDs with distance constraints as above can lead to BDDs that are exponential in size in the number of variables. The reason is that representing multiplication can lead to exponentially-sized BDDs, as proved in https://doi.org/10.1109/12.73590 .
If the constraints are not distance between points, but distance along each axis (i.e., an inequality or equality constraint on the absolute value of x1 - x2 or y1 - y2, or on both), then exponential complexity is avoided.
The above solves the placement problem over a mesh. This is a discrete placement problem. The continuous placement problem cannot be solved with binary decision diagrams, because it requires floating-point arithmetic.
The program above prints:

How add 0 when TruncWeek's week no result in Django Query?
I want query the issue's count of group by weekly.
query1 = MyModel.object.filter(issue_creator__in=group.user_set.all()).\
annotate(week=TruncWeek('issue_creat_date')).values('week').annotate(count=Count('id')).order_by('week'))
the query result is OK. the queryset result:
[
{'week': datetime.datetime(2022, 1, 3, 0, 0, tzinfo=<DstTzInfo 'Europe/Stockholm' CEST+2:00:00 DST>), 'count': 9},
{'week': datetime.datetime(2022, 1, 10, 0, 0, tzinfo=<DstTzInfo 'Europe/Stockholm' CEST+2:00:00 DST>), 'count': 12},

but 20220101-20220301 has 9 weeks:
[

how to write the right queryset?
Thanks.
Django method for None value Coalesce.
from django.db.models.functions import Coalesce

annotate(week=TruncWeek('issue_creat_date')).values('week').annotate(count=Count('id')).order_by('week'))
Chart.js: scrollable/swipable time-based x-axis
Let's say I have the following data set using a time based Cartesian x axis. Basically, these are data points spread over 3 days.
{x: new Date(2021, 2, 5, 0, 0), y: 9},
{x: new Date(2021, 2, 5, 2, 0), y: 7},
{x: new Date(2021, 2, 5, 5.5, 0), y: 4.3},
{x: new Date(2021, 2, 5, 7, 0), y: 6},
{x: new Date(2021, 2, 5, 8, 0), y: 3.7},
{x: new Date(2021, 2, 5, 14, 0), y: 9.5},
{x: new Date(2021, 2, 6, 4, 0), y: 4.0},
{x: new Date(2021, 2, 6, 11, 0), y: 5},
{x: new Date(2021, 2, 6, 12, 0), y: 2.7},
{x: new Date(2021, 2, 6, 14, 0), y: 1.7},
{x: new Date(2021, 2, 6, 19, 0), y: 5.7},
{x: new Date(2021, 2, 7, 17, 0), y: 6.7},
{x: new Date(2021, 2, 7, 21, 0), y: 5.7},
{x: new Date(2021, 2, 7, 22, 0), y: 4.7},
Lets say my starting view is the middle day, in this case day 6. Then I want a feature where you can swipe scroll to the next / previous day. Only 1 day should be shown in the graph at a time, unless you are scrolling / swiping between these.
Here is a simple sketch to illustrate this using the above data points.
Here are some other examples that show what I mean:
https://swipecalendar.io/. While this is a calendar, the idea should be clear and applicable to a line graph as well. You are swiping between 'months' and snapping to a month.
https://www.amcharts.com/demos/date-based-data/. Here you can see you can swipe along the x-axis and the time-span of the x-axis changes along while swiping (ignoring the 'full' graph' they have on the bottom).
Is something like this possible with Chartjs or with a plugin? I have not see any Chartjs examples that have a changing chart view based on a scroll state of the x-axis.
If not, is there recommendation for an alternative?
Please take a look at this plugin, https://github.com/chartjs/chartjs-plugin-zoom With this you can make the chart movable
Access Pandas MultiIndex column by name
I have a spreadsheet imported with pandas like this:
df = pd.read_excel('my_spreadsheet.xlsx',header = [0,1],index_col=0,sheetname='Sheet1')
The output of df.columns is:
MultiIndex(levels=[[u'MR 1', u'MR 10', u'MR 11', u'MR 12', u'MR 13', u'MR 14', u'MR 15', u'MR 16', u'MR 17', u'MR 18', u'MR 19', u'MR 2', u'MR 20', u'MR 21', u'MR 22', u'MR 3', u'MR 4', u'MR 5', u'MR 6', u'MR 7', u'MR 8', u'MR 9'], [u'BIRADS', u'ExamDesc', u'completedDTTM']],
labels=[[0, 0, 0, 11, 11, 11, 15, 15, 15, 16, 16, 16, 17, 17, 17, 18, 18, 18, 19, 19, 19, 20, 20, 20, 21, 21, 21, 1, 1, 1, 2, 2, 2, 3, 3, 3, 4, 4, 4, 5, 5, 5, 6, 6, 6, 7, 7, 7, 8, 8, 8, 9, 9, 9, 10, 10, 10, 12, 12, 12, 13, 13, 13, 14, 14, 14], [1, 2, 0, 1, 2, 0, 1, 2, 0, 1, 2, 0, 1, 2, 0, 1, 2, 0, 1, 2, 0, 1, 2, 0, 1, 2, 0, 1, 2, 0, 1, 2, 0, 1, 2, 0, 1, 2, 0, 1, 2, 0, 1, 2, 0, 1, 2, 0, 1, 2, 0, 1, 2, 0, 1, 2, 0, 1, 2, 0, 1, 2, 0, 1, 2, 0]],
names=[None, u'De-Identified MRN'])
I have been trying to access the values of column named 'De-Identified MRN', but can't seem to find the way to do this.
What I have tried (based on similar posts):
[in] df.index.get_level_values('De-Identified MRN')
[out] KeyError: 'Level De-Identified MRN must be same as name (None)'
and
[in] df.index.unique(level='De-Identified MRN')
[out] KeyError: 'Level De-Identified MRN must be same as name (None)'
UPDATE:
The following did the trick for some reason. I really do not understand the format of the MultiIndex Pandas Dataframe:
pd.Series(df.index)
By using your data
s="MultiIndex(levels=[[u'MR 1', u'MR 10', u'MR 11', u'MR 12', u'MR 13', u'MR 14', u'MR 15', u'MR 16', u'MR 17', u'MR 18', u'MR 19', u'MR 2', u'MR 20', u'MR 21', u'MR 22', u'MR 3', u'MR 4', u'MR 5', u'MR 6', u'MR 7', u'MR 8', u'MR 9'], [u'BIRADS', u'ExamDesc', u'completedDTTM']],labels=[[0, 0, 0, 11, 11, 11, 15, 15, 15, 16, 16, 16, 17, 17, 17, 18, 18, 18, 19, 19, 19, 20, 20, 20, 21, 21, 21, 1, 1, 1, 2, 2, 2, 3, 3, 3, 4, 4, 4, 5, 5, 5, 6, 6, 6, 7, 7, 7, 8, 8, 8, 9, 9, 9, 10, 10, 10, 12, 12, 12, 13, 13, 13, 14, 14, 14], [1, 2, 0, 1, 2, 0, 1, 2, 0, 1, 2, 0, 1, 2, 0, 1, 2, 0, 1, 2, 0, 1, 2, 0, 1, 2, 0, 1, 2, 0, 1, 2, 0, 1, 2, 0, 1, 2, 0, 1, 2, 0, 1, 2, 0, 1, 2, 0, 1, 2, 0, 1, 2, 0, 1, 2, 0, 1, 2, 0, 1, 2, 0, 1, 2, 0]],names=[None, u'De-Identified MRN'])"
idx=eval(s, {}, {'MultiIndex': pd.MultiIndex})
df=pd.DataFrame(index=idx)
df.index.get_level_values(level=1) # df.index.get_level_values('De-Identified MRN')
Out[336]:
Index(['ExamDesc', 'completedDTTM', 'BIRADS', 'ExamDesc', 'completedDTTM',

Also if all above still does not work , try
df.reset_index()['De-Identified MRN']
Try the following: midx = pd.MultiIndex( levels=[[u'MR 1', u'MR 10', u'MR 11', u'MR 12', u'MR 13', u'MR 14', u'MR 15', u'MR 16', u'MR 17', u'MR 18', u'MR 19', u'MR 2', u'MR 20', u'MR 21', u'MR 22', u'MR 3', u'MR 4', u'MR 5', u'MR 6', u'MR 7', u'MR 8', u'MR 9'], [u'BIRADS', u'ExamDesc', u'completedDTTM']], labels=[[0, 0, 0, 11, 11, 11, 15, 15, 15, 16, 16, 16, 17, 17, 17, 18, 18, 18, 19, 19, 19, 20, 20, 20, 21, 21, 21, 1, 1, 1, 2, 2, 2, 3, 3, 3, 4, 4, 4, 5, 5, 5, 6, 6, 6, 7, 7, 7, 8, 8, 8, 9, 9, 9, 10, 10, 10, 12, 12, 12, 13, 13, 13, 14, 14, 14], [1, 2, 0, 1, 2, 0, 1, 2, 0, 1, 2, 0, 1, 2, 0, 1, 2, 0, 1, 2, 0, 1, 2, 0, 1, 2, 0, 1, 2, 0, 1, 2, 0, 1, 2, 0, 1, 2, 0, 1, 2, 0, 1, 2, 0, 1, 2, 0, 1, 2, 0, 1, 2, 0, 1, 2, 0, 1, 2, 0, 1, 2, 0, 1, 2, 0]], names=[None, u'De-Identified MRN'] ) midx.levels[1] # returns the following Index(['BIRADS', 'ExamDesc', 'completedDTTM'], dtype='object', name='De-Identified MRN') midx.levels[1].values # returns the following array(['BIRADS', 'ExamDesc', 'completedDTTM'], dtype=object)
Django count number of records per day
I'm using Django 2.0
I am preparing data to show on a graph in template. I want to fetch number of records per day.
This is what I'm doing
qs = self.get_queryset().\
extra({'date_created': "date(created)"}).\
values('date_created').\
annotate(item_count=Count('id'))
but, the output given is
[
{'date_created': datetime.date(2018, 5, 24), 'item_count': 1},
{'date_created': datetime.date(2018, 5, 24), 'item_count': 1},
{'date_created': datetime.date(2018, 5, 24), 'item_count': 1},
{'date_created': datetime.date(2018, 5, 24), 'item_count': 1},
{'date_created': datetime.date(2018, 5, 24), 'item_count': 1},
{'date_created': datetime.date(2018, 5, 24), 'item_count': 1},
{'date_created': datetime.date(2018, 5, 24), 'item_count': 1}
]
Here data is not grouped and same date is returning repeatedly with count as 1
Try using TruncDate function. See that answer
Google Charts is not displaying last row in the data array?
I have data array with 45 rows but only 44 rows are visible on the screen after I am hide columns between 8 and 14 using "setColumns" and then re-enable any of the columns between 8 and 14:
The 45th row has following data:
0:{wf: "10 May 2018, 14:44:36"}
1:{wf: ""}
2:{wf: ""}
3:{wf: ""}
4:{wf: ""}
5:{wf: ""}
6:{wf: ""}
7:{wf: ""}
8:{wf: "69.9"}
9:{wf: "73.2"}
10:{wf: "65.2"}
11:{wf: "73.2"}
12:{wf: "82.8"}
13:{wf: "0"}
14:{wf: "28.6"}
To perform column toggle I use following commands:
performColumnToggle: function (col)
{
// use original unfiltered data
_view = new google.visualization.DataView(_original_data);
// get a key due to splice not keeping keys one delete
var key = $.inArray(col, _toggledColumns);
if (_columns[col]['status'] === 1) {
_columns[col]['status'] = 0;
// delete by key because splice doesn't keep keys on delete
_toggledColumns.splice(key, 1);
} else {
_columns[col]['status'] = 1;
// insert new items with a key and push other columns
_toggledColumns.splice(col, 0, col);
}
// set columns to display
_view.setColumns(_toggledColumns);
console.log(_chart.getDataTable().getNumberOfRows()); // keeps returns 44 rather then 45.
_dashboard.draw(_view);
}
I set _original_data when I first initiate the chart and when I have to update the data in the chart. When I perform console.log(_original_data) I see all 45 rows.
init_chart: function ()
{
_data = new google.visualization.DataTable(_tableData);
_original_data = _data;
// some other code ....
}
updateData: function ()
{
_tableData = data;
_data = new google.visualization.DataTable(_tableData);
_original_data = _data;
// some other code ....
}
Below is an example code
https://jsfiddle.net/Spiker/g0k714h7/
To trigger error take following steps:
Scroll down the page you will notice that we have 45 rows with last row having time date "10 May 2018, 14:44:36"
Scroll back up and click on "Select/Diselect All". You can scroll down the table to see that now we have 44 rows
Either Click on "Select/Diselect All" or "record8". Scroll down the page to see that we still have 44 rows in the table
DataView Class
.hideColumns() Method
DataView Class is a special version of the DataTable Class. Its main purpose is to present a part(s) of the DataTable(s). OP code needs to toggle columns with the method that compliments .setColumns() which is .hideColumns().
In Demo 1 below there is a ternary that toggles the columns from [0,...14] to [8...14] columns by using both set/hideColumns() methods. The table has 90 rows and it persists at 90 between toggling of columns.
Example
var dView = *status === 'on' ?
view.setColumns([0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14]) :
view.hideColumns([0, 1, 2, 3, 4, 5, 6, 7]);
⭐ Demo 2 (located at the bottom of this post,) isn't a solution but it could help the OP code should you decide on not using Demo 1.

⭐Although I strongly suggest that you use the hideColumns() from Google Visualization API, I'd like to address this:
"// delete by key because splice doesn't keep keys on delete "
splice() returns whatever it deletes. So you call on splice() and store its return in a var, const, array, object, etc.
Demo 2
var columnArray = [0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14];
var removedArray = columnArray.splice(0, 8);
console.log('Removed Column Array: ' + removedArray);
console.log('Remaining Column Array: ' + columnArray);
var restoredArray = removedArray.concat(columnArray);
console.log('Restored Column Array: ' + restoredArray);
the problem appears to occur in function --> switchOffAllColumns
there must be some sort of bug with the view
setting the view columns on the ChartWrapper, rather than the DataView,
corrects the issue
in switchOffAllColumns, change the following line...
_view.setColumns(_toggledColumns);
to...
_chart.setView({
columns: _toggledColumns
});
see following working fiddle...

note: jsapi should no longer be used, changed above fiddle to use loader.js load statement...
