 | `"Cumulative"` | The set `{(s, d, r, b) in Z^{3n+1}}`, representing the `cumulative` global constraint, where `n == length(s) == length(r) == length(b)` and `dimension = 3n + 1`. `Cumulative` requires that a set of tasks given by start times `s`, durations `d`, and resource requirements `r`, never requires more than the global resource bound `b` at any one time. | {"type": "Cumulative", "dimension": 10} |
 | `"Path"` | Given a graph comprised of a set of nodes `1..N` and a set of arcs `1..E` represented by an edge from node `from[i]` to node `to[i]`, `Path` constrains the set `(s, t, ns, es) in (1..N)times(1..E)times{0,1}^Ntimes{0,1}^E`, to form subgraph that is a path from node `s` to node `t`, where node `n` is in the path if `ns[n]` is `1`, and edge `e` is in the path if `es[e]` is `1`. The path must be acyclic, and it must traverse all nodes `n` for which `ns[n]` is `1`, and all edges `e` for which `es[e]` is `1`. | {"type": "Path", "from": [1, 1, 2, 2, 3], "to": [2, 3, 3, 4, 4]} |
