QUESTION

Polytope, Python - find extreme points

Asked 2022-Apr-08 at 11:22

I need to find a list of all the extreme points of a polytope given by a matrix relation Ax <= b, with x being non-negative. I know that 100% of the time, the polytope is non degenerate. The first solution I used was to generate a random non negative vector and run an LP with the vector being the objective function (so basically; optimizing in a random direction). This of course has many problems: take an insane amount of time and in the end I can't be sure the solution is correct.

Then I tried using the polytope toolbox; with the 'extreme' function. I ran it on an instance I already know well:

Your question is not clear (cf my comment) but you should use pycddlib. I tried and I got something close to your expectation:

QUESTION

Calculating the percentage of overlap between polytopes (n-dimensions)

Asked 2021-Jul-13 at 10:48

I have to figure out the percentage of overlap between polytopes in n-dimensional spaces, where my only available source of reference is a set of randomly sampled points within those polytopes.

Assume that the following two R objects are two sets of randomly sampled points from two different polytopes in 5 dimensions:

So, the most straightforward way is to use the hypervolume package.

Checking for the intersection of a 4D line segment and a 4D convex polytope

Asked 2020-Dec-21 at 10:03

I have two 4D shapes: a polytope composed of two triangles with each side connected to the corresponding side on the other triangle (think triangular prism, but not necessarily straight) and a line segment.

I don't need to know where they intersect, just whether they intersect or not. How can I check for this?

Your convex polytope is delimited by a number of hyperplanes, of equation ax+by+cz+dw+e = 0. Considering a point inside the polytope, you can adjust the signs so that all inside points verify ax+by+cz+dw+e ≥ 0 for all hyperplanes.

Now a line segment will have parametric equations like

Maximum volume inscribed ellipsoid in a polytope/set of points

Asked 2020-May-27 at 00:20

Later Edit: I uploaded here a sample of my original data. It's actually a segmentation image in the DICOM format. The volume of this structure as it is it's ~ 16 mL, so I assume the inner ellipsoid volume should be smaller than that. to extract the points from the DICOM image I used the following code:

The distance matrix you create is the problem for Concorde. Concorde should catch that and give an appropriate error message.

Vulnerabilities

No vulnerabilities reported

Install polytope

You can install using 'pip install polytope' or download it from GitHub, PyPI.
You can use polytope like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
