Abstract.
We introduce
the notion of a test tube system with objects (a TTO system for short), a distributed
parallel computing device operating with multisets of symbols, motivated by
characteristics of biochemical processes. We prove that these constructs are suitable for
computing, any recursively enumerable set can be identified by a TTO system. We also raise
some open questions arising from the unconventional nature of this computational tool.
