reader_lp.h File Reference

Detailed Description

LP file reader.

Author

Tobias Achterberg

This reader allows to parse and write CPLEX .lp files with linear and quadratic constraints and objective, special ordered sets of type 1 and 2, indicators on linear constraints, and semicontinuous variables. For writing, linear (general and specialized), indicator, quadratic, second order cone, and special ordered set constraints are supported.

The lp format is defined within the CPLEX documentation.
