Typedef Documentation

typedef std::function<bool(const Space& home, SetVar x, int i)> Gecode::SetBranchFilter

Branch filter function type for set variables.

The variable x is considered for selection and i refers to the variable's position in the original array passed to the brancher.

Definition at line 1083 of file set.hh.

typedef std::function<double(const Space& home, SetVar x, int i)> Gecode::SetBranchMerit

Branch merit function type for set variables.

The function must return a merit value for the variable x. The value i refers to the variable's position in the original array passed to the brancher.

Definition at line 1095 of file set.hh.

typedef std::function<int(const Space& home, SetVar x, int i)> Gecode::SetBranchVal

Branch value function type for set variables.

Returns a value for the variable x that is to be used in the corresponding branch commit function. The integer i refers to the variable's position in the original array passed to the brancher.

Definition at line 1108 of file set.hh.

typedef std::function<void(Space& home, unsigned int a, SetVar x, int i, int n)> Gecode::SetBranchCommit

Branch commit function type for set variables.

The function must post a constraint on the variable x which corresponds to the alternative a. The integer i refers to the variable's position in the original array passed to the brancher. The value n is the value computed by the corresponding branch value function.

Definition at line 1123 of file set.hh.
