Generating a graph with multiple (sets of multiple sets of multiple) X-axis data sets
by Aaviel in Programming Languages

I am looking for a way to generate a graph with multiple sets of data on the X-axis, each of which is divided into multiple sets of multiple sets. I basically want to take this graph and place similar graphs side by side with it. I am trying to graph the build a graph of the duration (Y-axis) of the same jobs (0-3) with different configurations (0-1) on multiple servers (each group with the s

Python - can't import Set from sets (“no module named sets”)
by Charlie98 in Programming Languages

I'm trying to learn python and I was trying to write something simple. I am developing under Pydev (Eclipse) using OS X 10.8. I installed python 3.2 using the 64bits .dmg installer.

I configured the Python interpreter successfully (or I think so, as I actually can create a "hello world" project and run it). But for some reason, when I try to import Set (from sets import Set

How to calculate difference between two sets in emacs lisp,the sets should be lists
by raven84 in Web Design

How to calculate the difference between two sets in Emacs Lisp? The sets should be lists.
The programm should be very simple and short, or else I won't understand it. I'm a newbee.


Refactor a couple of functions into one by accepting sets and returning sets
by chuck1723 in Programming Languages

I have a couple of functions which calculates different statistical data based on input dictionaries, e.g. max, min, sum, average, median.

I would like to combine all these functions into one instead of having them in different methods. so the caller can do something like below:

(minValue, averageValue, maxValue) = myFunction(min, avg, max, data, key, ...)

Is there any appproximate algorithms in set cover when there are too many sets, say, 2^n sets?
by Mexico in Programming Languages

I am recently working on a problem which I think is a fork of the set cover problem. However, the number of sets in my problem is as large as 2^n. And the approximate alogrithms I've found seem to be only effective when there are not too many sets. I wonder there exists an alogorithm that suits with 2^n sets?

Thank you for your answering!!!

Generate sets of sets of n-dimensional points
by Shantanu in Web Design

I am trying to take sets of points and split them up into smaller sets. The constraint is that each set has some minimum and some maximum for each of their dimensions. I want to generate all possible combinations of these sets (let's call this a set of sets.) When I am done, each point appears in exactly one set in each set o' sets.

As an example, let's say I just have data points t

Consolidating overlapping sets from an array of sets
by Enzo in Programming Languages

I have an array with each entry containing a minimum and a maximum value for a bunch of sets such as the one below:

[0] => Array
[0] => 1200
[1] => 2400
[1] => Array
[0] => 1400
[1] => 3800
[2] =&

Difference Between Comforter Sets & Duvet Sets
by Massachusetts in Home & Garden
Many people get confused over the difference between a comforter and a duvet cover. A comforter may be right for one person but not suit the taste of the next person at all. A proper explanation should guide you so that you make the right choice for your bedroom.

Calculate a set of concatenated sets of n sets
by South Korea in Programming Languages

Okay - I'm not even sure that the term is right - and I'm sure there is bound to be a term for this - but I'll do my best to explain. This is not quite a cross product here, and the order of the results are absolutely crucial.

Recreate sets from combinations of these sets
by Rahulmax in Development Tools & Services

I came across a specific problem and looking for some algorithm for it. The problem to solve is as described below.

Let's say we have combinations like below

1 - 3 - 5

1 - 4 - 5

1 - 8 - 5

2 - 4 - 5

3 - 4 - 5

2 - 4 - 7

These combinations were generated from given sets, in this particular case let's s
