Path finding in a graph (Transitive Closure)

// Datalog program for path-finding in a graph
//
// The program computes the transitive closure of
// a graph.
// -- relations --
// Edges of a graph
.decl edge(x:number, y:number)
// Path in a graph
.decl path(x:number, y:number)
// -- facts --
// A graph with 4 nodes and 4 edges
edge(1,2).
edge(2,3).
edge(3,4).
edge(4,1).
// -- rules --
// A path is an edge
path(x,y) :- edge(x,y).
// A path is a path followed by an edge
path(x,z) :- path(x,y), edge(y,z).
// -- output --
.output path()Real programs from Software Heritage
