Based on the dynamic program principle,the optimal sequence of a jeep problem is given.

One-way coupled mapping lattice model was first used to generate spatiotemporal chaos binary sequence and each performance of the sequence was analyzed,which proves that the chaos sequence has a good pseudo-randomicity.

This paper proposed three-dimensional tent map,which was based on unit cube,analysed the nature of the output sequences,and studied the relativity and balance of the binary sequence generated by the tent map.

Taking dual chaotic inter-perturbed system as sequence key generator,an improved quantization method for converting chaotic sequence to binary sequence was put forward.

In order to get binary sequences,which are random and sensitive to the initial values,this paper presents an approach of generating extended chaotic sequences based on Bernstein function and interpolation method.

In order to get binary sequences which are randomness,an extended method is presented,which can generate binary chaotic sequences nonlinearly based on chaotic dynamics systems,the sequences is randomness and sensitive to the initial conditions.

An improved chaotic binary sequences algorithm based on one four-dimension chaotic map is proposed.
