Truss Optimization using Genetic Algorithm
In this paper, a genetic algorithm is proposed to solve the weight minimization problem of truss structures
considering shape, and sizing design variables. Design variables are discrete or/and continuous. The design of truss
structures is optimized by an efficient optimization algorithm called Teaching-Learning-Based Optimization (TLBO). The
process of TLBO is divided into two parts: the first part consists of the „Teacher phase‟ and the second part consists of the
„Learner phase‟. Analyses of structures are performed by a finite element code in MATLAB which is used in conjunction
with an optimization code based on TLBO. The effectiveness of TLBO algorithm is demonstrated through benchmark truss
18-bar, and compare with results in references.
