Abstract The exponential growth of the power modern digital computers is based upon miniaturization vast nanoscale arrays electronic switches, but this will be eventually constrained by fabrication limits and dissipation. Chemical processes have potential to scale beyond these performing computations through chemical reactions, yet lack well-defined programmability their scalability performance. Here, we present a hybrid digitally programmable array as probabilistic computational machine that uses oscillators using Belousov-Zhabotinsky reaction partitioned in interconnected cells substrate. This architecture performs efficient computation distributing information between domains together with inbuilt error correction logic. efficiency gained combining logic on nearest neighbour interactions hysteresis effects. We demonstrated capabilities our processor implementing one- two-dimensional Cellular Automata demonstrating emergent dynamics life-like entities called Chemits. Additionally, demonstrate viable for solving combinatorial optimization problems.
