Function Documentation

void Gecode::precede ( Home  home,
const SetVarArgs &  x,
int  s,
int  t 
)

Post propagator that s precedes t in x.

This constraint enforces that if there exists $j$ such that $s\notin x_j\land t\in x_j$, then there exists $i<j$ such that $s\in x_i\land t\notin x_i$.

void Gecode::precede ( Home  home,
const SetVarArgs &  x,
const IntArgs &  c 
)

Post propagator that successive values in c precede each other in x.
