Re: how to define integer polytope by matrix representation

Dear Thomas, Many thanks for your clarifying where I was doing wrong. It now makes sense as the two different methods (matrix & in/eq form) could produce the same solution. Would you say places, where I can find the related documents about what Dr. Joswig mentioned for the polyhedron specifications?...

Re: how to define integer polytope by matrix representation

Dear Prof. Joswig, Many thanks for your detailed explanation. As I am pretty new in this field, what you answered is very interesting to me. Would you say please, how we can find the related documents about the interpretation of the vertices method? I mean, how can I find the number of vertices, ray...

Re: how to define integer polytope by matrix representation

Dear support team, Thanks for your helpful answer. I have tried this and works well, but I have an issue with calculating the vertices by defining the polyhedron based on both methods. Let's say, in the first attempt, I define the problem by the following method: // $p = new Polytope(INEQUALITIES=>[...

how to define integer polytope by matrix representation

Dear support team, First, thanks for your useful tool. I am trying to define a polyhedron (actually, integer polytope) by using "https://shell.polymake.org/". I would like to represent the polyhedron of the GAP (generalized assignment problem) that is defined by the following constraints: // CPLEX l...
