چکیده

Protein Folding is a broad research field in computational Biology, Molecular Biology and Bioinformatics. Protein Folding Optimization is one of the NP-hard problems. Bio-inspired metaheuristics plays a major role in solving the protein folding optimization which can mimic the insect’s problem solving abilities like foraging, nest building and mating. In this paper Ant Colony Optimization (ACO) Metaheuristic was applied to solve 3D-HP protein folding optimization. The 3D structure of a protein is also called as final native structure, which is responsible for functioning of a particular protein. Misfolded or unfolded protein is responsible for several neurodegenerative diseases. The instances for 3D-HP protein folding were taken from the HP benchmarks. The energy minimization is the major objective function to obtain the best 3D structure of protein. Various energy functions are used in this work to obtain different energy values.

An Improved Ant Colony Optimisation Algorithm for the 2D HP Protein Folding Problem

The prediction of a protein’s structure from its amino-acid sequence is one of the most important problems in computational biology. In the current work, we focus on a widely studied abstraction of this problem, the 2-dimensional hydrophobic-polar (2D HP) protein folding problem. We present an improved version of our recently proposed Ant Colony Optimisation (ACO) algorithm for this -hard combi...

Parameter Optimization of Pso for Protein Structure Prediction Problem in the 2d Hp Model

Proteins are considered the most important molecules found in living cells because they are fundamental to many of the life processes. In order to accomplish their tasks, proteins fold in their native state, which is the three-dimensional arrangement of their atoms in which the protein reaches its minimum energy. The protein structure prediction (PSP) problem consists in finding the native stat...
