In this article, I want to talk about one of the easiest ways to find paths for a two-dimensional map. I do not take into account the greedy search algorithm because of its simplicity and not optimality. Today we will talk about the algorithm for finding the shortest paths from one vertex of the graph to all the others, proposed by the Dutch scientist Edsger Wybe Dijkstra. Also, I will show you A* algorithm, based on Dijkstra.
There is an ancient tradition in mathematics to place an operator between the operands (x + y)
rather than after
the operands xy+
. Form with an operator between operands is called infix notation. The form with an operator
after the operands is called postfix, or Reverse Polish notation. It has a number of advantages over infix
notation when expressing algebraic formulas:
- Any formula can be expressed without parentheses.
- It is convenient for calculating formulas on stacked machines.
- Infix operators have precedence that is arbitrary and undesirable.

Kruskal's algorithm - efficient algorithm for constructing the minimum spanning tree of a weighted connected undirected graph. The algorithm is also used to find some approximations for the Steiner problem.
The algorithm solves the problem of finding the minimum spanning tree (MST).
