Games, puzzles, and computation
… Logic formalism to many actual games and puzzles, providing new hardness proofs. These applications include sliding-block puzzles, sliding-coin puzzles, plank puzzles, hinged polygon dissections, Amazons, Kohane, Cross Purposes, Tip over, and others.

Subway Shuffle, 1 × 1 Rush Hour, and Cooperative Chess Puzzles: Computational Complexity of Puzzles
… motivated by three applications of proving other puzzles hard. A fairly straightforward reduction shows that the puzzle game Rush Hour is PSPACE-complete when all of the cars are 1 × 1 and there are fixed immovable cars. We show that two classes of cooperative Chess puzzles, helpmates and …

Immaterialist solutions to puzzles in personal ontology
… personal ontology. We will see from these puzzles in personal ontology that materialist solutions are either unsuccessful or yield unacceptable consequences. This should prompt us toward considering, instead, immaterialism. According to immaterialism, persons are not material objects, and …

Examining financial puzzles from an evolutionary perspective
In this thesis, we examine some puzzles in finance from an evolutionary perspective. We first provide a literature review of evolutionary psychology, and discuss three main findings; the frequentist hypothesis, applications from risk-sensitive optimal foraging theory, and the cheater detection …

Solving general game playing puzzles using heuristics search
… Game Playing (GGP) is to effectively solve puzzles. Solving puzzles is more similar to planning algorithms than the search methods used for two- or multi-player games. General problem solving has been a topic addressed by the planning community for years. In this thesis we adapt heuristic …

A system for procedurally generating puzzles for games
… tools and libraries for procedurally generating puzzles for video games and interactive fiction. The system has the goals of producing solvable and flexible general-purpose puzzles through the use of simple tools targeted at small development teams. The system is implemented as two graphical …

Mitigating Network-Based Denial-of-Service Attacks with Client Puzzles
… client puzzle protocols: Puzzle TCP and Chained Puzzles. Puzzle TCP, or pTCP, is a modification to the Transmission Control Protocol (TCP) that supports the use of client puzzles at the transport layer and is designed to help combat various DoS attacks that target TCP. In this protocol, when a …

An investigation into the solution to, and evaluation of, Kakuro puzzles
Kakuro puzzles, also known as Cross-Sum puzzles, are similar in structure to standard Crossword puzzles. They consist of grids, containing overlapping continuous runs that are exclusively<br/>either horizontal or vertical, with “clues” to the completion of numerical “words”. The numerical clues …

On the computational complexity of portal and push-pull block puzzles
… on the game mechanics allowed. Push-pull block puzzles are games, similar to Sokoban, which involve moving a 'robot' on a square grid with obstacles and blocks that can be pushed or pulled by the robot into adjacent squares. We prove that push-pull block puzzles in 3D and push-pull block puzzles …

Unraveling the puzzles of spectroscopy-based non-invasive blood glucose detection
Disorders of glucose homeostasis, including types 1 and 2 diabetes, represent a leading cause of morbidity and mortality worldwide. Diagnosis and therapeutic monitoring of diabetes requires direct measurement of blood glucose. Regardless of the clinical test performed, however, withdrawal of blood …

A Narrative Inquiry Into Curriculum-Making Experiences With Games and Puzzles in a Mathematics Class
… curriculum-making experiences with games and puzzles in a mathematics class. For sixteen weeks I lived alongside a teacher and children in a fifth-grade class exploring what curriculum unfolds when interactive games and puzzles are introduced into a mathematics class. When it came time to …

Pueblos, Planets, and Permian Puzzles: The Perils and Promise of Analogical Evidence in the Historical Sciences
How do scientists investigate the deep past when material traces are fragmentary and direct experimentation is impossible? This thesis explores the epistemic role of analogical reasoning in historical science, arguing that analogy is not merely interpretive but can function as a method of …
