net.sf.cpsolver.coursett.criteria.BrokenTimePatterns
public class BrokenTimePatterns
Broken time patterns. This criterion counts cases when an unused space is in a room
which follows one of the standard MWF or TTh pattern. E.g., there is a penalty of
Monday is available during a time when Wednesday and/or Friday is occupied. The aim
is to use this space if possible in order to leave the available space in a way that
can be used by MWF or TTh classes.
