Abstract: In order to solve the problem of sketch constraint quickly and efficiently, a hybrid Newton iterative algorithm based on artificial bee colony is proposed to solve the sketch constraint problem. It first uses the colony algorithm to search the initial value, and obtains the initial value as the initial value of the Newton method to solve the problem of the sketch constraint, which ensures the iterative speed and fully combines the advantages of the two to achieve the goal of speed and success. The simulation results show that the algorithm is reliable and has strong numerical stability. It is a good method to solve the problem of sketch constraint.
