Teaching Learning Based Optimization (TLBO) method is an evolutionary algorithm that simulate the teaching–learning behavior of the students of a classroom. This MATLAB code implements the basic TLBO algorithm for truss optimization problem. However the code could be easily extended to solve other optimization problems. HelpTLBO.mp4 explains how to use the code. More details about TLBO method could be find in the following reference:

A more efficient TLBO algorithm is also introduced in the following reference:
