Solving scientific and engineering problems from the real world is a very complicated task, currently; hence, development of powerful search optimization techniques great importance [...]

this article presents the application of two algorithms: heuristic big bang-big crunch (hbb-bc) and a heuristic particle swarm ant colony optimization (hpsaco) to discrete optimization of reinforced concrete planar frames subject to combinations of gravity and lateral loads based on aci 318-08 code. the objective function is the total cost of the frame which includes the cost of concrete, formw...

in this paper, the problem of layout optimization for x-bracing of steel frames is studied using the ant system (as). a new design method is employed to share the gravity and the lateral loads between the main frame and the bracings according to the requirements of the ibc2006 code. an algorithm is developed which is called optimum steel designer (osd). an optimization method based on an approx...

In practical system identification, process optimization and controller design, it is often desirable to simultaneously handle several objectives and constraints. In some cases, these objectives and constraints are non-commensurable and they are not explicitly/mathematically available. This paper proposes a new subjective optimization method based on interactive evolutionary computation (IEC) t...

We have recently demonstrated that evolutionary algorithms can be used to modify the excitation applied to a structure such that damage detection resolution on the output will be improved. Recent results indicate that optimized inputs are highly sensitive to the damage detection feature employed in the optimization, implying that the excitation and feature type should be closely matched if impr...

Glued-Laminated Timber (GLULAM) is a widely-used building material, popular for its strength, durability, and sustainability. It created by bonding together layers of wood, making it common choice civil structures. In this study, Bi-directional Evolutionary Structural Optimization (BESO) proposed to improve the performance GLULAM By positioning steel bars within structure, objective increase st...

Sediment rating curve (SRC) is a conventional and a common regression model in estimating suspended sediment load (SSL) of flow discharge. However, in most cases the data log-transformation in SRC models causing a bias which underestimates SSL prediction. In this study, using the daily stream flow and suspended sediment load data from Shalman hydrometric station on Shalmanroud River, Guilan Pro...
