NAME ^

Freecell::App - A simple Freecell solver.

VERSION ^

Version 0.01

SYNOPSIS ^

Please run the script freecell-solver to call this module.

EXPORT ^

none.

SUBROUTINES/METHODS ^

solve()

The solver is a breadth-first search using an A* heuristic to score the tableau so that the number of positions on the stack can be trimmed to the maxnodes by their score. This is necessary to prevent out_of_memory.

search()

Call generate_nodelist() then play() each node and append the autoplay() moves. Store the new Tableau in the position hash if it is not a duplicate. The key for the position hash is create by to_token() and the fields stored in the position hash are [ depth, token, node, score, 0 (place holder for level used later during trim) ] If one of the new positons solve the hand, then call backtrack() to build the solution array and then call out() to write the html. Set found to true.

backtrack($key)

This takes the final key and calls undo() until the initial position is reached and pushes each node onto the solutions array.

out(@solution)

Writes the html solution to disk.
