This means that one can move back and forth between an inequality\nrepresentation and a generator (i.e. vertex and ray) representation of a\npolyhedron with cddlib. Also, cddlib can solve a linear programming problem,\ni.e. a problem of maximizing and minimizing a linear function over P.\n","package_architecture":"amd64","stem":"cddlib","readme":null,"dependencies":[{"path":"devel/gmp","type":"library","package_spec":"","url":"/packages/current/devel/gmp/"},{"path":"devel/metaauto","type":"build","package_spec":"","url":"/packages/current/devel/metaauto/"},{"path":"devel/autoconf/2.69","type":"build","package_spec":"","url":"/packages/current/devel/autoconf/2.69/"},{"path":"devel/automake/1.16","type":"build","package_spec":"","url":"/packages/current/devel/automake/1.16/"},{"path":"devel/libtool","type":"build","package_spec":"","url":"/packages/current/devel/libtool/"},{"path":"devel/gmake","type":"build","package_spec":"","url":"/packages/current/devel/gmake/"}],"reverse_dependencies":{"count":0,"url":null},"categories":["math"],"flavors":[],"only_for_architectures":["aarch64","amd64","arm","i386","mips64","mips64el","powerpc","powerpc64","riscv64","sparc64","alpha","hppa"],"not_for_architectures":[]}}
