The hardest logic puzzle ever becomes even tougher

Why the Hardest Logic Puzzle Ever Cannot Be Solved in Less than Three Questions

Rabern and Rabern (2008) and Uzquiano (2010) have each presented increasingly harder versions of 'the hardest logic puzzle ever' (Boolos 1996), and each has provided a BLOCKIN BLOCKIN two-­‐question BLOCKIN BLOCKIN solution BLOCKIN BLOCKIN to BLOCKIN BLOCKIN his BLOCKIN BLOCKIN predecessor's BLOCKIN BLOCKIN puzzle. BLOCKIN BLOCKIN But BLOCKIN BLOCKIN Uzquiano's BLOCKIN BLOCKIN puzzle BLOCKIN BL...

Why Even the Logic of Re-Defined Choice May Still Contradict the Logic of Care in Public Health Systems?

Comparison of parametric and fuzzy analytic hierarchy process in land evaluation (Case study: Varamin region)

In last decades, the skillful planning of land resources has become a major issue for rural development. The development of cultivated areas becomes gradually impossible due to ever increasing population growth and urban development. Fuzzy logic is preferred to Boolean logic for land evaluation, because fuzzy techniques lead to estimate for land use suitability on a continuous scale and can the...

Habilitationsschrift zur Erlangung der Venia legendi der Fakultät für angewandte Wissenschaften der Albert-Ludwigs-Universität Freiburg für das Fach Informatik Heuristic Search

This article surveys approaches to cope with limited memory for the design of algorithms and data structures in Artificial Intelligence, since many systems, e.g. in puzzle solving, two-player games, action and route planning, robotics, machine learning, data mining, logic programming and theorem proving, explore very large or even infinite implicitly given state spaces. The main focus is on str...

The Thermodynamic Arrow: Puzzles and Pseudo-puzzles

For more than a century, physics has known of a puzzling conflict between the T-asymmetry of thermodynamic phenomena and the T-symmetry of the underlying microphysics on which these phenomena depend. This paper provides a guide to the current status of this puzzle, distinguishing the central issue from various issues with which it may be confused. It is shown that there are two competing concep...
