dsdp-theta — Compute the Lovasz Theta number of a graph
Synopsis
dsdp-theta [Options] GRAPH_FILE
Description
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.
Options
- -dloginfo N
Set the logging level (default 0). More information is printed for higher numbers.

Read DSDP parameters from FILE
- -help

File Format
The input file should be in the following format:
n m
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.
