Because repression of a jumping gene also affects genes located near it on the chromosome, the researchers suspect that these repressors have been co-opted for other gene-regulatory functions, and that those other functions have persisted and evolved long after the jumping genes the repressors originally turned off have degraded due to the accumulation of random mutations.
Among the topics are the performance comparison of jumping gene adaptations of an elitist non-dominated sorting genetic algorithm, a robust multi-objective genetic algorithm with online approximation under interval uncertainty, chance constrained programming to handle uncertainty in nonlinear process models, the ecodesign of chemical processes with multi-objective genetic algorithms, and the multi-objective optimization of a hybrid steam stripper-membrane process for the continuous purification of bioethanol.
