The problem of predicting a protein structure with minimum energy from a sequence of amino acids has a significant importance in biology. This is a computationally challenging problem being NP-hard even in simplified lattice protein models such as the hydrophobic-polar (HP) model. We investigate the performance of hybrid evolutionary algorithms in the context of the bidimensional HP model. A new fitness function to evaluate the quality of a protein conformation is proposed and engaged in a hybrid evolutionary model to address protein structure prediction. The evolutionary model relies on hill-climbing strategies integrated in the search operators and a meaningful diversification of genetic material. The proposed fitness takes into account the energy of the conformation as well as the existence of a certain conformation H core on the HP lattice. The resulting weighted fitness function is able to guide the evolutionary search in a more efficient way as emphasized by computational experiments.
