+ - `pathfinding` package solve path finding problem by shortest path algorithm, one point to another
+ - To solve multiple nodes problem, use concept from reinforcement learning
+ - Build Q function that represents total reward of choosing certain path to be solved first
+ - Update Q function in a loop with certain amount of episodes
+ - Choose the order of solving paths randomly, and add possibility of choosing it from Q function
+ - Exploration-exploitation method
+- To solve the problem "convert dxf to matrix" for pathfinding:

+ - Resolution problem: single point does not represented as a pixel in `png`
