crash with glpk and OSSolverService
envoyé par gmail.com
I encounter a (pure binary LP) problem with glpk solver through
COIN-OR services. Please find the input problem in both (please mail
me for getting these files < 100 Kb, i put a copy of these in FILES
section of this google group)
1 - CPLEX format : sheet-0-problem.cplex
2 - OSIL format :sheet-0-problem.osil
When I try to solve my problem with regular glpk command line tool :
$ glpsol --version
GLPSOL: GLPK LP/MIP Solver, Version 4.26
$ glpsol --cpxlp sheet-0-problem.cplex
...
INTEGER OPTIMAL SOLUTION FOUND
...
It works fine. While I submit this problem through OSSolverService to
glpk, it is making glpk crash :
$ OSSolverService -solver glpk -osil sheet-0-problem.osil -osrl
sheet-0-problem.osrl
...
Start Solve with a Coin Solver
SOLVER NAME = glpk
CREATING A NEW OPTIMIZATION SOLUTION
ipp_basic_tech: 0 row(s) and 0 column(s) removed
GLPK internal error: ipp != ipp; file glpk/src/glpipp02.c, line 803
Aborted
Please note other solvers (-solver cbc, -solver symphony, -solver
cplex) employed with OSSolverService succeeded !
