Constructor Detail

ShortTableCT

public ShortTableCT(IntVar[] x,
                    int[][] table,
                    int star)

Create a Table constraint with short tuples.

Assignment of x_0=v_0, x_1=v_1,... only valid if there exists a row (v_0|*,v_1|*, ...) in the table.

Parameters:

x - the variables to constraint. x must be non empty.

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

star - the * symbol representing "any" value in the table
