dsdp-theta [Options] GRAPH_FILE
The dsdp-theta program uses the DSDP library to compute the Lovasz Theta number of an input graph. This number is an upper bound for the maximum clique of a graph, a lower bound for the minimal graph coloring, and serves as a bound for several other combinatorial graph problems. The number is the solution to a semidefinite program.
The input file should be the complement of the graph. This file also demonstrates the use of customized data matrices in DSDP.

The input file should be in the following format:
r1 c1 [w1]
im jm [wm]
where n is the number of nodes, and m is the number of edges. Each r/c pair or r/c/w triple describes one edge, where r is the row, c is the column, and w is the weight. The weight is ignored, if present.
