On the Turing Completeness of Transformers and Agents

It is shown that a single fixed finite precision transformer cannot memorize certain Turing machines with inputs of arbitrary length, such as the arithmetic; and a single fixed infinite precision transformer trained with a random algorithm is not Turing complete with probability one under reasonable conditions.

MechMath Agent Team: LLM Driven Agents for Mathematical Research

The MechMath Agent Team (MMAT) is presented, which is a large language model driven agent designed to serve as a co-pilot throughout the full cycle of mathematical research, and a tripartite Harness Architecture that decouples system responsibilities into Control, Execution, and Augmentation planes, thereby reconciling...
