First,we constructed a pair of appropriate upper and lower solutions,and then we proved the existence of the traveling wave solutions between two equilibria of the system by using the monotone iteration approach.

This paper is devoted to investigate a kind of lattice Nicholson s blowflies model with delay,and prove the existence of traveling wavefronts by upper-lower solution and monotone iteration technique.

It is shown that the system exist monotone traveling wave solutions by using monotone iteration with upper and lower solutions provided wave speed satisfies some conditions.

The method of upper and lower solutions and the monotone iterative technique are used.

By using cone theorem and monotone iterative method, the mixed monotone condition in A(x,y)+Mx in Banach spaces is extended.

It obtains the existence results by using the monotone iterative method of lower and upper solutions and improves the results.

Some methods like linear prediction,iteration adjustment and recovery of missing feature points are summarized from the experiment ,with which the LSM method is improved.

Multi-robot system is uniformly distributed along the circle by iteratively adjusting each side and the inner angle of the polygon if the number of robots is not too much.
