A Polynomial-Time Reduction from the 3SAT Problem to the Generalized String Puzzle Problem

A Polynomial-Time Reduction from the 3SAT Problem to the Generalized String Puzzle Problem

A disentanglement puzzle consists of mechanically interlinked pieces, and the puzzle is solved by disentangling one piece from another set of pieces. A string puzzle consists of strings entangled with one or more wooden pieces. We consider the generalized string puzzle problem whose input is the lay...
