Function Documentation

void Gecode::channel ( Space *  home,
const IntVarArgs &  x,
const IntVarArgs &  y,
IntConLevel  icl = ICL_DEF,
PropKind  pk = PK_DEF 
)

Post propagator for $ x_i = j\leftrightarrow y_j=i$ for all $0\leq i<|x|$.

  • Supports domain (icl = ICL_DOM) and value propagation (all other values for icl).
  • Throws an exception of type Int::ArgumentSizeMismatch, if x and y are of different size.
  • Throws an exception of type Int::ArgumentSame, if x or y contain the same unassigned variable multiply. Note that a variable can occur in both x and y, but not more than once in either x or y.
