Complex task computing migration method based on edge environment reliability constraint

The invention provides an edge environment reliability constraint complex task calculation migration method in the technical field of computers. The method comprises steps of S10, obtaining a task setto construct a complex workflow model; S20, constructing a parent population based on the complex workflow model and initializing the parent population; S30, generating a mixed population based on the parent population; S40, sorting the individuals of the mixed population by using a third-generation non-dominated sorting genetic algorithm to form a plurality of non-dominated layers; S50, calculating an extreme point of each optimization target of the mixed population; and S60, constructing a three-dimensional coordinate plane based on each extreme point, calculating an intercept value from acoordinate axis to the three-dimensional coordinate plane, and performing iterative updating on the parent population by utilizing the intercept value and the non-dominated layer. The method is advantaged in that the system en
