Evolution strategies

The hybrid evolutionary algorithm for 2S-MILPs is realized by using an evolution strategy (ES) to solve the master problem of the intensive 2S-MILP. Each individual of the ES represents a first-stage candidate solution x. The object parameters are encoded by a mixed-integer vector. The fitness of an individual is evaluated by the objective function of the master problem (MASTER),/ (x).

The ionisation process of the NaK dimer is investigated by applying evolution strategies to optimize the spectral phase of fs pulses interacting with the molecules. The obtained optimal pulse structure with three intensity maxima is presented. As an explanation of the ionization process a simple model of wave packet propagation on given potential energy surfaces is proposed.

Based on these arguments, we developed the simple directed evolution strategy illustrated in Fig. 1 [2, 6], In comparison to the enzyme performing a function for which it is selected in nature, the new job is performed poorly indeed.

Evolution strategies (ESs) were developed in the 1960s, at around the same time as early work on GAs. In its first form, ES was not really an EA, more a slightly disguised, moderately sophisticated hill-climber however, it has since metamorphosed into a true EA through the use of a population of potential solutions and a more sophisticated evolutionary mechanism.
