Graph Realization Programs


Graph Realization Problem (GRP) is the following:
    Given a {0,1}-matrix A,
    decide whether A is a fundamental circuit matrix of a certain graph or not, and if so, construct such a graph.

The source codes below, written by Takahiro Ohto in 2003, implement two almost linear-time algorithms by Bixby and Wagner[1] and Fujishige[2]. See [3,4] for details.
Please check README file before using the programs.
