1Adaptability or versatility
If personal computers are used to simulate algorithms, then computation can be performed, but memory cannot be expanded to accommodate increasing storage needs
Solution Approach 1:
The patent replaces mechanical and electronic memory systems with a chemical system based on the Belousov-Zhabotinsky reaction. Chemical concentrations represent data states, and chemical reactions perform computation, eliminating the need for traditional expandable memory hardware while achieving universal Turing machine functionality through chemical processes
Solution Approach 2:
The invention uses changes in chemical concentrations and reaction rates as dynamic parameters to represent and process information. By varying chemical species concentrations in the BZ reaction system, the machine can encode different data states and perform computations without requiring additional physical memory storage capacity
2Adaptability or versatility
If a chemically-operated Turing machine is constructed, then memory limitations are overcome and general chemical computation is achieved, but device complexity increases
Solution Approach 1:
The patent implements a universal chemical computer based on the Belousov-Zhabotinsky reaction that can perform any computation given appropriate chemical programming. The same chemical system handles multiple functions including memory storage, logic operations, and state transitions, achieving Turing completeness without requiring separate specialized components for each function
Solution Approach 2:
The invention introduces chemical species as intermediaries that mediate between input data and computational results. Chemical reactions serve as the intermediary process that transforms input chemical concentrations through a series of controlled reactions to produce output concentrations representing computed results, enabling complex computations through simple chemical interaction rules

AI summary
The present disclosure relates to a Turing machine having a reactor comprising a reactant solution comprising a reactant;a first chemical species source to provide a selected amount of a first chemical species;a second chemical species source to provide a selected amount of a second chemical species;one or more controllers coupled to control the addition of the first and second chemical species from the first and second chemical species sources responsive to an input; and a sensor positioned to sense changes in the reactant as the controller controls the first and second chemical species sources to add selected amounts of the respective first and second chemical species to the reactor. The controller receives signals corresponding to the state of the reactant and correlates the states of the reactant to a result that is computed as a function of the input.
