glpk: return NAs for unfeasible problems

Wed Aug 27 02:48:42 CDT 2008

hi,

when dealing with an unfeasible problem that is detected by GLPK
presolver, the return vectors xmin, fmin, extra.lambda and
extra.redcosts are not filled, thus they contain random garbage on
return. Attached is a patch that initialized these vectors by the NA
value.

regards,
