Detailed Description

Typedef Documentation

◆ FloatBranchFilter

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 1448 of file float.hh.

◆ FloatBranchMerit

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 1461 of file float.hh.

◆ FloatBranchVal

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 1487 of file float.hh.

◆ FloatBranchCommit

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 1502 of file float.hh.
