It is commonly believed that information processing in living organisms is based on chemical reactions. However, the human achievements in constructing chemical information processing devices demonstrate that it is difficult to design such devices using the bottom-up strategy. Here I discuss the alternative top-down design of a network of chemical oscillators that performs a selected computing task. As an example, I consider a simple network of interacting chemical oscillators that operates as a comparator of two real numbers. The information on which of the two numbers is larger is coded in the number of excitations observed on oscillators forming the network. The parameters of the network are optimized to perform this function with the maximum accuracy. I discuss how information theory methods can be applied to obtain the optimum computing structure.
人们普遍认为，生物体中的信息处理是基于化学反应的。然而，人类在构建化学信息处理设备方面的成果表明，使用自下而上的策略来设计此类设备是困难的。在此，我讨论一种执行选定计算任务的化学振荡器网络的替代自上而下设计。作为一个例子，我考虑一个简单的相互作用化学振荡器网络，它作为两个实数的比较器运行。关于这两个数中哪个更大的信息被编码在构成网络的振荡器上观察到的激发次数中。对网络的参数进行优化，以最高精度执行此功能。我讨论了如何应用信息论方法来获得最佳计算结构。
