Solving Constraint Integer Programs 1.1.0 (Default branch)
SCIP (Solving Constraint Integer Programs) is a framework for constraint integer programming oriented towards the needs of mathematical programming experts who want to have total control of the solution process and access detailed information down to the guts of the solver. It integrates techniques from mixed integer programming, constraint programming, and SAT solving. It can also be used as a pure MIP solver or as a framework for branch-cut-and-price. In order to use it, you have to link to an LP solver. It currently supports CLP, CPLEX, Mosek, Soplex, and XPress-MP. License: Free for non-commercial use Changes:
New constraint handlers for SOS constraints. Better support for compilation of projects using SCIP. SCIP can now count integer solutions. A column generation example for graph coloring has been added. Extended output capabilities. Support for Pseudo-Boolean problems. New heuristic DINS. New cutting plane separator MCF. Improved sorting functions. Revised preprocessing. Reworked timing calls. LP-interfaces adapted to Clp and SoPlex. Many internal performance improvements and bugfixes.

CLP(1) General Commands Manual CLP(1) NAME
clp - linear program solver SYNOPSIS
clp filename [ options ] solutionfile DESCRIPTION
This manual page documents briefly the clp command. clp -- interface to the coin linear programming solver. clp solves the following linear optimization program: minimize c^t x such that: row_lb <= Ax <= row_ub column_lb <= x <= column_ub OPTIONS
When no options are given clp enters the interactive command line mode. Otherwise the program enters a batch mode, for which a summary of options is included below. For a complete description, see /usr/share/doc/coinor-libclp-doc. -help Show summary of options. -primalsimplex solve the problem using the primal simplex method -dualsimplex solve the problem using the dual simplex method -maximize maximize the problem SEE ALSO
glpsol(1),dsdp5(1) This program is fully documented in the accompanying html documentation which can be found in /usr/share/doc/coinor-libclp-doc if the coinor-libclp-doc package is installed. AUTHOR
