## Abstract

The invention discloses a variance reduction technology-based distributed projection method considering communication time delay. The method comprises the following steps of 1, proposing an original optimization problem model (1) for a multi-intelligent system with local set constraints and local equation constraints at the same time; 2, equivalently converting the original optimization problem model (1) obtained in the step 1 into a convex optimization problem model (2) convenient for distribution processing; step 3, proposing a variance reduction technology-based distributed projection algorithm (3), solving a constrained convex optimization problem model (2), i.e., estimating a local full gradient in an unbiased manner by adopting a local random average gradient so as to reduce a heavycalculation burden caused by calculating full gradients of all local target functions in each iteration; and 4, performing convergence analysis. According to the invention, the calculation cost of allagents in the network can be greatly reduced, so that the communication and calculation pressure of the whole multi-agent system is reduced, and the practicability is relatively high.
