#148 closed defect (migrated)

Standalone solver option nodeStrategy broken for up/down selection

Description

Some of the values for this option are updepth, downdepth, upfewest, downfewest.

The code to distinguish the up/down direction seems to depend on the parity of the integer representing the option value, but this is the code:

int way = (((nodeStrategy - 1) % 1) == 1) ? -1 : +1; babModel_->setPreferredWay(way);

It seems that this should instead be:

int way = (((nodeStrategy - 1) % 2) == 1) ? -1 : +1; babModel_->setPreferredWay(way);
