Integer sets.
Integer sets are the means to specify arbitrary sets of integers to be used as domains for integer variables.
| Gecode::IntSet::IntSet | ( | void | ) | [inline] |
Initialize as empty set.
Definition at line 47 of file int-set-1.hpp.
| Gecode::IntSet::IntSet | ( | int | n, |
| int | m | ||
| ) | [inline] |
Initialize as range with minimum n and maximum m.
Note that the set is empty if n is larger than m
Definition at line 101 of file int-set-1.hpp.
| Gecode::IntSet::IntSet | ( | const int | r[], |
| int | n | ||
| ) | [inline] |
Initialize with n integers from array r.
