2023-03-02extra reductionsJSDurand
Finished the function of performing extra reductions. Still untested though.
2023-02-27before a major refactorJSDurand
I decide to adopt a new approach of recording and updating item derivation forests. Since this affects a lot of things, I decide to commit before the refactor, so that I can create a branch for that refactor.
2023-02-13Fix phantom edgesJSDurand
Previously there was a minor bug: if the chain-rule machine ended in a node without children, which node should be accepting because of edges that have no children and hence were ignored, then since the node has no children, it would be regarded as not accepting. Now this issue is fixed by introducting real or imaginary edges, where an imaginary edge is used to determine the acceptance of nodes without chidlren.
2023-02-12fix clone not changing the rootJSDurand
Previously cloning a node does not alter the root of the forest, while it should alter the root if the cloned node was the root. This would affect how we compare the equalities of forests. It indeed resulted in anomalies that were hard to solve.
2023-02-12Added the functionality of split or clone.JSDurand
I need more than the ability to clone nodes: I also need to split the nodes. Now this seems to be correctly added.
