| | | | | Another proof idea using finite automata Steve Cook proved three landmark theorems with 1971 dates. The first has been called a "surprising theorem": that any deterministic pushdown automaton with two-way input tape can be simulated in linear time by a random-access machine. This implies that string matching can be done in linear time, which inspired... | |

| | | | | [AI summary] The article discusses the debate around whether CSS3 is Turing complete, focusing on Eli Fox-Epstein's implementation of a Rule 110 automaton using CSS and HTML. It explains the theoretical concepts of Turing completeness, the limitations of real-world implementations, and the implications of such a claim. The author concludes that CSS appears to be Turing complete, though the discussion highlights the complexities and controversies surrounding this assertion. | |

Computational problems come in all different types and from all kinds of applications, arising from engineering as well the mathematical, natural, and social sciences, and involving abstractions such as graphs, strings, numbers, and more. The universe of potential algorithms... | |
