约170勘探地震资料和测井资料的分析和显示功能（加上他们所谓的支持功能）的设置。这些功能读取和写入标准的SEG - Y格式的地震数据，读取和写入测井在LAS格式2.0（也读3.0 LAS格式），并执行许多通常对这些数据类型进行的操作。他们使用标准化的结构来表示地震数据和测井数据，从而使函数调用的简单串联。(A set of about 170 functions (plus support functions called by them) for analysis and display of exploration-seismic data and well logs. These functions read and write seismic data in standard SEG-Y format, read and write well logs in LAS-format 2.0 (also read LAS-format 3.0), and perform many of the manipulations usually performed on these data types. They use standardized structures to represent seismic data and well data and thus allow simple concatenation of function calls.)

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.
