Constructor Detail

NegTableCT

public NegTableCT(IntVar[] x,
                  int[][] table)

Negative Table constraint.

Assignment of x_0=v_0, x_1=v_1,... only valid if there does not exists a row (v_0, v_1, ...) in the table. The table represents the infeasible assignments for the variables.

Parameters:

x - the variables to constraint. x is not empty.

table - the array of invalid solutions (second dimension must be of same size as the array x)
