The puzzle method was introduced by Choi and Park as an effective method for finding nonsingular characteristic maps over wedged simplicial complexes K( J) obtained from a given simplicial complex K. We study further the mod 2 case of the puzzle method. We firstly describe it completely in terms of linear algebraic language which allows us to develop a constructive puzzle algorithm. We also analyze our algorithm and compare its performances with other known algorithms including the Garrison and Scott algorithm.
