Ticket Resolution Summary Owner Reporter
#11 fixed Preflow and Tolerance Peter Kovacs Alpar Juttner
Description

The Tolerance can cause a bug in the Preflow algorithm. If there is no edge with epsilon or more capacity the source node can have surely positive excess. I think the algorithm should revised with the tolerance class and it would be nice to prove the correctness and the time complexity of the algorithm with tolerance.

The test generator could be found in my home dir.

#12 fixed compiling under MSdev Akos Ladanyi Alpar Juttner
Description

The following change are necessary to compile lp_glpk under MSdev:

-lp_glpk.cc(67):    int ind[LEMON_glp(get_num_cols)(glp.lp)];
-lp_glpk.cc(68):    Value val[1+LEMON_glp(get_num_cols)(glp.lp)];

+lp_glpk.cc(67):   int* ind=new int[LEMON_glp(get_num_cols)(glp.lp)];
+lp_glpk.cc(68):   Value* val=new Value[1+LEMON_glp(get_num_cols)(glp.lp)];
+lp_glpk.cc(91):	delete [] ind; delete [] val;

I do not even understand how can it be compiled under gcc?
