[Coin-discuss] Bugs in OsiGlpk

[Tim Hultberg]

I have encountered what seems to be 2 bugs in OsiGlpk:

1.
When using OsiOsl both alternatives below work fine.
a.
     CoinPackedMatrix A(true,m,n,Cst[n],Elm,Rnr,Cst,Clg);
     Solver->loadProblem(A, l, u, c, bl, bu);
b.
     Solver->loadProblem(n, m, Cst, Rnr, Elm, l, u, c, bl, 
bu);

When using OsiGlpk, only a. works.

2.
When using OsiGlpk for MIP, the solution which is reported 
is the solution of the LP-relaxation (although the correct 
problem is being solved!).
