A Chain-Detection Algorithm for Two-Dimensional Grids
  We describe a general method of detecting valid chains or links of pieces on
a two-dimensional grid. Specifically, using the example of the chess variant
known as Switch-Side Chain-Chess (SSCC). Presently, no foolproof method of
detecting such chains in any given chess position is known and existing graph
theory, to our knowledge, is unable to fully address this problem either. We
therefore propose a solution implemented and tested using the C++ programming
language. We have been unable to find an incorrect result and therefore offer
it as the most viable solution thus far to the chain-detection problem in this
chess variant. The algorithm is also scalable, in principle, to areas beyond
two-dimensional grids such as 3D analysis and molecular chemistry.
