Member Function Documentation

void Gecode::BoolVar::init ( Space home,
int  min,
int  max 
)

Initialize Boolean variable with range domain.

The variable is created with a domain ranging from min to max. The following exceptions might be thrown:

  • If min is greater than max, an exception of type Gecode::Int::VariableEmptyDomain is thrown.
  • If min is less than 0 or max is greater than 1, an exception of type Gecode::Int::NotZerOne is thrown.
