## Project: Tiling of Polyominoes

### Goal

Analyze, study and implement an algorithm for tiling a prescribed region or the entire (Euclidean) plane using zero or more copies of polyominoes from a given set of polyominoes. What are polyominoes? A polyomino is a plane geometric figure formed by joining one or more equal squares edge to edge.

### Main Results in Detail

A function (growUniverse) was created in the Wolfram Language that grows the tiled region by tiling along the perimeter. The following functions helped create the growUniverse function: allTiles[tile], positionTile[tile,{x,y},{w,h}], usedSpace[region], usedRange[region], findPerimeter[region], scanRange[tile,space], addTile[tile,region,{x,y}], detectVoid[region], score[region], scoreImg[region], addNextTile[region,tiles], putUniverse[universe,region,{x,y}], takeUniverse[universe, {x,y},{w,h}], increaseSpace[space,direction,length].

### Future Work

Optimize the function to improve speed.
