Custom Query (545 matches)

INVALID is used many times in LEMON codes and it could be annoying (we have to write capital letters using the Shift key). However, it could be avoided if the iterator classes converted to bool, thus we could write

for(NodeIt n(g); n; ++n)

instead of

for(NodeIt n(g); n!=INVALID; ++n)

Of course, this interface would be just an alternative for the current one.

This ticket is a follow-up of #246.

Namely, the changesets [f2d6d3446adf] and [4137ef9aacc6] from #268 are worth considering for backport to LEMON-1.0.

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.
