How to pathfind with volatile probabilities (Slay the spire)
I'm attempting to write an AI for the game Slay the Spire. One of the tasks it will need to do is navigate the map. The map is a directed acyclic graph with the same start and end node.
Each node (...

Are there any pathfinding algorithms that take customized rules into account when determining the shortest path?
I need a pathfinding algorithm that considers the history of visited nodes and varies its path depending on some rules (like already visited). Are there good approaches serving this purpose?
To be ...

Given an image and two points $A$ and $B$ on that image, how could we find a path from $A$ to $B$?
If we have a search or path-finding problem, A* and Dijkstra's algorithm require that we formulate it as a search in a graph with nodes and connections between these nodes. If there are obstacles, we ...
