An algorithm outputting all safe partial solutions is called ... They can be interpreted as directed graphs, by viewing each set as a node, and each membership relation as a directed edge between the ...

From here graph theory got expanded and generalized ... improvement to this basic algorithm is probably the A* algorithm (geometric goal directed search), which was developed in 1968 at Stanford ...

Mathematicians have long sought to develop algorithms that can compare any two graphs. In practice, many algorithms always ...
