This is a Hybrid PSO GSA Aigorithm.A new hybrid population-based algorithm (PSOGSA) is proposed with the combination of Particle Swarm Optimization (PSO) and Gravitational Search Algorithm (GSA). The main idea is to integrate the ability of exploitation in PSO with the ability of exploration in GSA to synthesize both algorithms’ strength. Some benchmark test functions are used to compare the hybrid algorithm with both the standard PSO and GSA algorithms in evolving best solution.

 检查数据：如果某一组转速N下数据点少于5个点，给出提示：“数据点少不能绘制曲线”。  插值：每一条转速N线上的测量点个数可能不一样，按照测量点数最多的个数，将测量点少的数据插值成测量数据点最多一样的个数 ( check data: If a group speed N under the data point is less than 5 points, hints: " The few data points can not draw a curve. The  interpolation: each a speed N line, the number of measurement points may be different, in accordance with the maximum number of measurement points, the measurement point less data is interpolated to the measurement data points up the same number of)
