Blocks world

The algorithm is similar to a set of wooden blocks of various shapes and colors sitting on a table.

Instead of rejecting the challenge at all the idea is to invent an easy to solve domain which is called a toy problem.

Its major advantage over more realistic AI applications is, that many algorithms and software programs are available which can handle the situation.

In its basic form, the blocks world problem consists of cubes in the same size which have all the color black.

[4] From an algorithm perspective, blocks world is an NP-hard search and planning problem.
