脉冲暂态混沌神经网络（PTCNN）是对暂态混沌神经网络的改进，呈现丰富的动力学性质，具有很强的跳出局部最小点的功能，在解决无约束非线性规划问题时，可以找到包括全局和局部最小值的尽量全面的最优解。当遇到带约束条件的非线性规划问题时，只有对约束条件进行合理处理，才能更有效地解决约束非线性规划问题。文章使用惩罚函数方法对含有约束条件的非线性规划问题进行处理，将其变成一个不含约束条件的非线性规划问题，进而用PTCNN求解，得到了令人满意的结果。

Pulse Transiently Chaotic Neural Network (PTCNN) can find almost all optima including the part optima and the global with its abundance dynamical characteristic, when is used in nonlinear non-constrained optimization. The optimization problem is first unconstrained by virtue of non-differentiable exact penalty function, and is further solved by PTCNN. It is showed by an example that this method is efficient.
