Description

A basis status of a column or row is one of the following three possibilities:

  • The col/row is on the upper bound (not in the basis)
  • The col/row is on the lower bound (not in the basis)
  • The col/row is in the basis

The basis query function should reflect this.

This ticket is a copy of report #38 of the old bug tracking system. It refers to svn trunk -r2710.

Hasn't this issue been solved by the redesign of the LP interface ([ed54c0d13df0])?

It is solved already, it has currently five states (basis, lower, upper, fixed, free).
