Studying the complexity of adapting to changing environments and optimizing gameplay strategies in such dynamic settings could be a fruitful area of research. By exploring these and other Tetris variants from a computational complexity perspective, researchers can gain a deeper understanding of the challenges and opportunities presented by different game mechanics and variations, leading to advancements in game design, AI gameplay, and algorithm development.

Khái niệm cốt lõi

Tetris clearing is NP-hard and #P-hard even when the piece types are restricted to any size-2 subset of the seven Tetris piece types. The results also hold under the "hard drops only" and "20G" models for certain piece type subsets.

Tóm tắt

The paper proves that Tetris clearing is NP-hard and #P-hard even when the piece types are restricted to any size-2 subset of the seven Tetris piece types. The key insights are:

For every size-2 subset of piece types, the authors provide a reduction from 3-Partition with Distinct Integers to Tetris clearing. The reduction involves constructing "bottles" with a neck portion and a body portion, and using a sequence of pieces to properly block all but one bottle, fill the unblocked bottle, and then reset the state of the bottles.
The authors also prove that 3-Partition with Distinct Integers and Numerical 3-Dimensional Matching with Distinct Integers are strongly ASP-complete, which is a stronger result than the previous strong NP-completeness proofs.
For certain size-3 subsets of piece types, the authors further establish ASP-completeness of Tetris clearing, which implies NP-hardness of finding another solution given k solutions, for any k≥0, as well as #P-completeness.
The authors also study Tetris under the "hard drops only" and "20G" models, and establish NP-hardness of both Tetris survival and clearing for certain size-2 subsets of piece types under these models.
