Gecode::Int::GCC::HallInfo Class Reference

List of all members.

Detailed Description

Container class provding information about the Hall structure of the problem variables.

This class is used to keep the number of different arrays small, that is an array of type HallInfo replaces integer arrays for each of the class members.

Member Data Documentation

Represents the union of all lower and upper domain bounds.

critical capacity pointer t represents a predecessor function where $ t_i $ denotes the predecessor of i in bounds

Definition at line 538 of file gccbndsup.icc.

difference between critical capacities

d_i is the difference between the capacities of hall[i].bounds and its predecessor in bounds hall[t[i]].bounds

Definition at line 546 of file gccbndsup.icc.

Hall set pointer.

If hall[i].h < i then the half-open interval [hall[h[i]].bounds,hall[i].bounds) is containd in a Hall set. Otherwise holds a pointer to the Hall intervall it belongs to.

Stable Set pointer.

Definition at line 560 of file gccbndsup.icc.

Potentially Stable Set pointer.

Definition at line 565 of file gccbndsup.icc.

Bound update.

newBound contains either a narrowed domain bound or is stores the old domain bound of a variable.
