Removal of Lineality Space

Hello Polymakers, Are there any routines in Polymake to remove the lineality space from the input polyhedron (in constraint form), so that the resultant is a full dimensional one? Is it right that a "gaussian elimination" algorithm should be able to do the same, with cubic complexity? Than...

google groups as archive

Hello Moderators,

Maybe you could consider archiving the forum on google groups. It has a more standard interface in which one can search for past messages.

Just a suggestion!

Orthant and Origin along with the polytope

Hello Polymakers (after a long time),

Could someone please let me know of any trick by which I can visualize the orthant system (and the origin as well) along with the polytope?

Thanks

pre-loading with script containing user written routines?

Hello Polymake users, I have a couple of routines to print my polytopes in a separate file. Is there anyway I can make polymake load this file when I start polymake by giving this file name at command line? I tried with --script option, but it seems to be doing something else. Thanks for the help Re...

Re: Segmentation fault and 2.9.9 vs. 2.9.10

Sorry, the second code should be the following: $another_poly=new Polytope<Rational>(VERTICES=>[[-1,0,0], [1,-1,0], [-4,1,0], [1,0,-1], [-2,0,1], [-7,1,3]]); print $another_poly->N_FACETS; print $another_poly->FACETS; print $another_poly->SIMPLE; print $another_poly->F_VECTOR; print $another_poly->H...

Segmentation fault and 2.9.9 vs. 2.9.10

Hello, Could someone help me on why the following codes segv? I am using 2.9.9. (I think I could be doing something trivially incorrect as for similar simple examples, polymake was running fine a couple of days back.) Also, I would like to know if 2.9.10 is an actual alpha release. This is because i...

Visualizing Cones

Hello, I am a new user of Polymake and am fascinated by it! Thanks to the authors. I have a simple questions to begin with, as my current work involves (homogeneous) cones and their polars and I am having trouble using "polytope versions" of them. Could someone help me on some tricks on ho...
