Ticket #2084 (closed defect: invalid)

Opened 13 years ago

Last modified 8 years ago

MIP heuristic DOA

Reported by: jeckstei Owned by: jwatson
Priority: normal Milestone:
Component: PICO Version: PICO 1.2.1
Keywords: Cc: pico-developers@…
Subcomponent: Source Code

Description (last modified by wehart) (diff)

Since the autoconfiscation, the MIP heuristic does nothing but throw exceptions like

ERROR! Caught `runtime_error' exception: (PN0) ../../../include/pico-milp/PicoLPInterface.h:1601: PicoLPInterface::delRowinfo -- Bad index rank 130

This needs to be tracked down!

Converting all severities into priorities and deprecating the severity field.

  • Owner changed from jeckstei to jwatson
  • Status changed from new to assigned
  • Milestone changed from PICO 1.3 to PICO 1.4

I'm reassigning this to Jean-Paul since the MIP heuristic is, as far as I can tell, now merged into the feasibility-pump heuristic. The initial problem of running is likely not an issue anymore. However, I'm leaving the ticket for now to represent the desire to have the Eckstein-Nediak heuristic available in some form.
