Thank you for the bug report.
Could you please provide the following information:
a) which version of glpk you are using? (Just type 'glpsol -v'.)
I use the version 4.25. I can use the version 4.27.
b) which glpk api routines were called since the last successful call
to glp_simplex (or lpx_simplex, or lpx_warm_up)?
Let,
glp_prob * glpkProbPtr;
glp_smcp glpkParamPtr;
I use:
glpkParamPtr.presolve=GLP_OFF;
int ret=glp_simplex(glpkProbPtr,&glpkParamPtr);
if (ret == GLP_EBADB){
ret = lpx_warm_up(glpkProbPtr);
if (ret == LPX_E_BADB){
lpx_std_basis(glpkProbPtr);
if(glp_simplex(glpkProbPtr,&glpkParamPtr)!=0)
cout<<"could not solve LP"<<endl;
}
}
