Signed p-adic Residual Encodings of Finite-Domain All-Different Systems with a Sudoku Case Study

A paper submitted to arXiv on 13 Sep 2026 introduces signed, weighted affine p-adic residual objectives as native encodings of finite-domain constraints, with a coordinatewise domination theorem guaranteeing every global minimiser lies in the finite domain. The authors report that in that domain the loss equals, up to an additive constant, the all-different conflict count or the negative number of satisfied CNF clauses, and they present standard Sudoku as an 81-coefficient case study requiring no one-hot lift. A client-side implementation exposes the generated dataframes, arithmetic, diagnostics, and searches.

Abstract:We study signed, weighted affine $p$-adic residual objectives as native encodings of finite-domain constraints. For primes that separate the finite alphabet, sufficiently weighted positive unary rows pin each coefficient to its allowed set, while negative rows reward unequal endpoints or clause satisfaction. A coordinatewise domination theorem places every global minimiser in the finite domain; there the loss is, up to an additive constant, the all-different conflict count or the negative number of satisfied CNF clauses. Standard Sudoku provides an $81$-coefficient case study without a one-hot lift. A client-side implementation exposes the generated dataframes, arithmetic, diagnostics, and searches.
