#50: declares node limit reached for an infeasible problem
--------------------+-------------------------------------------------------
Reporter: asm4 | Owner: tkr
Type: defect | Status: new
Priority: normal | Milestone:
Component: Master | Version: 5.2
Severity: normal | Keywords:
--------------------+-------------------------------------------------------
for some infeasible problems with node limit, symphony declares node limit
reached (instead of 'the problem is infeasible!'). Running with verbosity
12 suggests that feasibility is lost and the node is fathomed correctly.
to replicate:
run symphony with node_limit of 1 and input file:
/home/asm4/p0033.modified
The problem has feasible lp solution but becomes infeasible on adding
cuts.
