Cumulative with fd variable durations only works if the resource limit is one. I've tried both lib(cumulative) and lib(edge_finder3) with the same results. This is correct: [eclipse 6]: [X, Y] :: 1..5, D :: 4..6, cumulative([X, Y], [D, D], [1, 1], 1), D#>=5. no (more) solution. This is not: [eclipse 8]: [X,Y,Z]::1..10, D :: 4..6, cumulative([X, Y,Z],[D,D,D],[1,1,1],2), D#>=5. X = X{[1..10]} Y = Y{[1..10]} Z = Z{[1..10]} D = D{[5, 6]} There are 9 delayed goals. Do you want to see them? (y/n) The same behaviour is exhibited with D::5..6 initially. -- _______________________________________________________________ Dr. Mark Wallace, IC-Parc, Phone +44 (0)20 7594 8434 William Penney Laboratory, Fax +44 (0)20 7594 8432 Imperial College, London SW7 2AZ, UK.
