problem.chgrowstatus

Purpose

Change the status setting of a constraint

Synopsis

problem.chgrowstatus (rowindex, status)

Arguments

rowindex

The index of the matrix row to be changed.

status

The bitmap with the new status settings. If the status is to be changed, always get the current status first (use problem.getrowstatus) and then change settings as required. The only settings likely to be changed are:

Bit 11

Set if row must not have a penalty error vector. This is the equivalent of an enforced constraint (SLPDATA type EC).

Example

The following example changes the status of row 9 to be an enforced constraint.

status = p.getrowstatus (9)
status = status | (1<<11)
p.chgrowstatus (9, status)

Further information

If status is None the current status will remain unchanged.
