Typedef Documentation

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

Branch filter function type for float 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 1442 of file float.hh.

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

Branch merit function type for float 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 1455 of file float.hh.

typedef std::function<FloatNumBranch(const Space& home, FloatVar x, int i)> Gecode::FloatBranchVal

Branch value function type for float 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 1481 of file float.hh.

typedef std::function<void(Space& home, unsigned int a, FloatVar x, int i, FloatNumBranch nl)> Gecode::FloatBranchCommit

Branch commit function type for float 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 nl is the value description computed by the corresponding branch value function.

Definition at line 1496 of file float.hh.
