An Eight-Year-Old Polyomino Tiling Algorithm: Backtracking Search with Heuristics

2025-03-15

This article details an algorithm for solving the polyomino tiling problem. The core idea is to transform the geometric problem into a graph theory problem and use a backtracking search algorithm with various heuristics. First, the algorithm preprocesses to calculate all possible placements, constructing a bipartite graph representing all possibilities. Then, a backtracking search algorithm finds a subset of placements satisfying the conditions, optimized by heuristics such as prioritizing constrained grid points and splitting the grid. The algorithm demonstrates good generality and robustness in handling arbitrary grid shapes and polyomino sets. The author also discusses limitations and future improvements, such as transforming the problem into a SAT problem for solution.

The Exploding Cost of Disability in America: A Hidden Welfare System?

Over the past three decades, the number of Americans receiving disability benefits has skyrocketed, a trend at odds with medical advancements and anti-discrimination laws. This article investigates the reasons behind this surge, starting with a case study in Hale County, Alabama, revealing the ambiguity in disability definitions and the role of doctors. The author argues that in some areas, disability assessments have become a de facto welfare program, particularly for unemployed individuals lacking education and job skills. The piece explores how factory closures have driven workers onto disability, and how a private company facilitates the transfer of welfare recipients into the disability system. Ultimately, the article points to a lack of a comprehensive plan to address the growing disabled population and the exorbitant costs involved, highlighting the disability system as an expensive default solution threatening the sustainability of social security.

Atari ST and DOS PCs: A Forgotten Disk Compatibility Story

In 1984, Atari faced a challenge in getting an operating system for the Atari ST. Due to time constraints, they partnered with Digital Research, opting for their nearly-complete GEM OS instead of the then-unfinished Windows. GEM would later be ported to PCs, but it didn't gain traction. However, Atari ST's use of GEMDOS, similar to PC-DOS, and the identical disk format, allowed for surprisingly easy file transfers between the Atari ST and PCs. Despite minor compatibility issues, this was revolutionary at the time and remains relevant today. The article also recounts an attempt to run DOS programs on an Atari ST using pc-ditto, a third-party emulator. While slow, the ability to run some DOS applications showcases the Atari ST's unique charm in the retro computing world.
