The papers in this special section were presented at the ieee BIBM 2014 conference that was held in Belfast, U.K., from November 18–22, 2014. The scientific program highlights five themes to provide breadth, depth, and synergy for research collaboration: 1) genomics and molecular structure, function, and evolution; 2) computational systems biology; 3) medical informatics and translational bioinformatics; 4) cross-cutting computational methods and bioinformatics infrastructures; and 5) healthcare informatics.

The study and analysis of functional annotations of human genes and gene variants are important for understanding functional genomics and gene-disease associations. This paper investigates the process of functional annotation of gene variants using the gene ontology. The paper also presents a method for annotating gene variants with biological process terms from the gene ontology. The presented method relies on identifying the enriched biological processes of the genes associated with the given genetic variants. With significant level of p<0.02, the results found to be biologically significant. Furthermore, we found that certain ontology annotations e.g. {GO:0031325;positive regulation of cellular metabolic process} are more connected with mutations via certain genes compared with normal biological process terms in the gene ontology.

Recent work in representation has developed small, evolvable structures called a complex string generator that generate infinite, aperiodic strings of characters. Such a string can be sectioned to provide an arbitrary list of parameters of indefinite length. Other work in evolving networks to model disease transmission has an issue common in many high-dimensional problems, evolution is less efficient when it must get a large number of parameter values correct. Specifying many parameters with a small evolvable object is a potential solution to this problem. In this study we compare three different implementations of representations, two of which employ complex string generators, to specify social contact graphs that plausibly explain the pattern of infection in a small epidemic. Representations that edit a starting network are found to have results that clump in network space while evolving the adjacency matrix provides increased diversity: none of the representations overlap in their results. The adjacency matrix based representation also generated outliers that outperform a baseline representation, probably because of its enhance diversity of solutions.

Protein-protein interactions can be modeled as networks. The huge amount of produced Protein-Protein Interaction (PPI) data has many applications in biological studies. These studies improved human knowledge in the life process and diseases. One of these studies is PPI network alignment, which finds the similarity between PPI networks as a biological similarity. Aligning these networks is important to investigate evolutionary pathways or protein complexes. The main challenge of all global PPI network alignment is to improve both accuracy and efficiency. In this research, the accuracy and efficiency of global PPI network alignment are improved by using the genetic algorithm instead of the greedy algorithm and applied in HubAlign framework. The performance of the proposed method is compared with HubAlign based on the total execution time for the alignment process and the correctness of the results of the aligned networks. The new approach enhanced the overall accuracy and reduce execution time compared to the HubAlign approach.

This study introduces a new game that models competition in foraging behavior. Two moose decide, in each time period, which of three foraging areas to visit. Moose in the same foraging area fight, gaining no forage and also damaging some forage during their conflict. Moose alone in a foraging area eat, with the forage in each field being replenished with a logistic growth model. This creates a relatively complex game with a rich strategy space in which the moose try to maximize their forage intake. The game is a coordination game, as the moose try to avoid conflict which does not maximize forage intake. The paper reports the results of two student competitions at Innopolis University and performs agent evolution to verify the existence of a rich strategy space for the game.

bioinformatics and computationalbiology are two fast-growing fields that require the direct application of computationalintelligence. The American patent system is currently going through the biggest reformation since the passage of Patent Act of 1952, and thus intellectual property rights (IPR) and strategies continue to be increasingly vital in these fields. In order to better understand the status quo of intellectual property (IP) specifically in the fields of biology that apply computationalintelligence, basic IP definitions, recent IP developments, and advanced protection strategies are presented and discussed.

This study performs simulations inspired by the reported genome meltdown of a small population of woolly mammoths prior to their extinction. These simulations test the interaction of population size, mutational diameter, and fitness change on two types of fitness landscapes. The first landscape studies a population initialized at a global optimum to assess fitness loss, while the second uses an open-ended function with no global optimum to assess the degree of adaptive radiation possible with different population sizes. Both an age structured non-elitist evolutionary algorithm and a evolutionstrategy like biased random walk are used. The simulations demonstrate that small populations are substantially worse at retaining fitness when initialized in a global optimum but also have a substantially greater potential for adaptive radiation and discovery of new niches.

Network graphs appear in a number of important biological data problems, recording information relating to protein-protein interactions, gene regulation, transcription regulation and much more. These graphs are of such a significant size that they are impossible for a human to understand. Furthermore, the ever-expanding quantity of such information means that there are storage issues. To help address these issues, it is common for applications to compress nodes to form supernodes of similarly connected components. In previous graph compression studies it was noted that such supernodes often contain points from disparate parts of the graph. This study aims to correct this flaw by only allowing merges to occur within a local neighbourhood rather than across the entire graph. This restriction was found to not only produce more meaningful compressions, but also to reduce the overall distortion created by the compression for two out of three biological networks studied.
