The difficulty of puzzle rings is mainly due to the complexity of the solving procedures and the high number of dimensions of the possible moving paths. This paper aims at providing a quantitative evaluation of the concept of puzzle ring difficulty, and proposes some feature values for describing the difficulty. Furthermore, the effectiveness of those(More)
The difficulty of puzzle rings is mainly due to the complexity of the solving procedures and the dimensions of the possible moving paths. This paper aims at quantitative evaluation of the puzzle ring difficulty. We propose some feature values to express the difficulty. Then, effectiveness of those values is evaluated by comparing with how difficult we feel(More)
