Abstract

The LEGO Construction Problem is the problem of deciding which bricks to place where in a predefined LEGO construction. The input consists of coloured voxels that each correspond to the size of a LEGO unit, such that all LEGO bricks are multiples of this LEGO unit. A solution to the LEGO Construction Problem is feasible if all bricks are within the design domain, the bricks do not overlap, the bricks satisfy the colour constraints, and all bricks connect into a stable construction.
