Abstract
A hybrid computer automatically connecting a plurality of computing elements, for example integrators of an analog computer by an instruction signal from a digital computer to perform a desired computation is equipped with an automatic control system for the mode control of the integrators of the analog computer. When the digital computer decodes a program written in a simulation language and supplies an instruction signal to the automatic control system, the automatic control system controls the mode of the integrators of the analog computer based on the instruction signal.
