A* Search algorithm in F#.
An implementation of the classic algorithm, as described here: https://en.wikipedia.org/wiki/A*_search_algorithm.
However, in contrast to the pseudo-code shown in that article, this version is implemented in a purely functional and immutable way, as is more idiomatic for F#.
The core code is in the src/AStar.fs/AStar module. The algorithm requires callers submit a start point, goal point, and three functions: a gscore calculator, fscore calculator and a method that returns the neighbours of a given point. In this way, the algorithm is generalisable to any type of point or graph structure - the only constraint on the generic point type is that it be comparable.
samples/Program.fs contains a console application demonstrating use of the algorithm, finding a path through a two dimensional grid.
This project can be used from nuget: https://www.nuget.org/packages/astar-search/1.0.2
Changes from 1.0.1
The core algorithm wasn't using tail recursion, which could cause stack overflows over large problem spaces. This has been fixed.
