This sounds quite similar to pure functional languages like Haskell, where a function call cannot have any side effect. But those go further in that they don't even have any mutable data. Instead of var foo = { a: 1 }; var ba

Ben Lynn's page https://crypto.stanford.edu/~blynn/compiler/ compiles (a large subset of) Haskell to web assembly (which you can download; a prime number sieve yielded 40KB of code) and runs it in the browser

Among 4 pawns like white and black a&b pawns, you only need 1 pawn capture to allow the other 3 pawns to promote.

To make this work, the rook can only have the king's position, if neither the king nor that rook have moved.

96 bits is not nearly enough, as there are ~4.8 * 10^44 > 2^148 legal chess positions (with side to move/castling/ep info) [1]. Chess Position Ranking provides a 153 bit encoding but it's very slow to decode. If the encodi

Closer to n3 or n5 I would think. Intel's node numbering is far more aspirational than TSMCs.

The proof of Lemma 1 says that a string of length n can be output by a program of length n+O(1) in any Turing complete programming language, but that ignores the fact that nearly all languages require certain characters in string literals t

The hashing rate is not directly relevant. That's roughly proportional to the daily dollar value of the reward times the efficiency of the leading mining hardware. The latter has gone up many orders of magnitude over the years. > bl
