is_combinatorial: Check if the an imset is structural or combinatorial

In rje42/imset: Methods for imsets with mixed graphs

Check if the an imset is structural or combinatorial

Description

Uses linear programming to check whether imsets can be decomposed as elementary imsets.

Usage

is_combinatorial(imset, timeout = 60L, sparse = FALSE)

is_structural(imset, timeout = 60L, sparse = FALSE)

imset_degree(imset, timeout = 60L)

Arguments

imset	an imset to be tested
timeout	an integer giving the maximum run time for each linear program in seconds
sparse	should sparse matrices be used?

Details

For the timeout operator to work we require version 5.6.13.4.9000 of lpSolve to be installed.

Functions

• is_structural(): test if imset is structural

• imset_degree(): for a structural imset, get its degree
