library(ic_edge_finder3)

Cubic edge-finder algorithm for disjunctive and cumulative constraints for IC

Predicates

cumulative(+StartTimes, +Durations, +Resources, ++ResourceLimit)
Cumulative constraint on specified tasks.
cumulative(+StartTimes, +Durations, +Resources, +Areas, ++ResourceLimit)
Cumulative constraint on specified tasks.
disjunctive(+StartTimes, +Durations)
Constrain the tasks with specified start times and durations to not overlap in time.
disjunctive_bools(+StartTimes, +Durations, ?OrderingBools)
Constrain the tasks with specified start times and durations to not overlap in time.

Description

This library implements the cubic edge-finder algorithm for the disjunctive and cumulative scheduling constraints for the IC solver. It provides the strongest propagation of the three libraries for cumulative constraints: ic_cumulative, ic_edge_finder and ic_edge_finder3. It is also computationally the most expensive. Note that the same predicates are implemented in both ic_edge_finder and ic_edge_finder3 libraries.
