makeECRMonitor

Monitor objects serve for monitoring the optimization process, e.g., printing
some status messages to the console. Each monitor includes the functions
<code>before</code>, <code>step</code> and <code>after</code>, each being a function and expecting
a log <code>log</code> of type <code>ecr_logger</code> and <code>...</code> as the only parameters.
This way the logger has access to the entire log.

Framework for building evolutionary algorithms for both single- and multi-objective continuous or discrete optimization problems. A set of predefined evolutionary building blocks and operators is included. Moreover, the user can easily set up custom objective functions, operators, building blocks and representations sticking to few conventions. The package allows both a black-box approach for standard tasks (plug-and-play style) and a much more flexible white-box approach where the evolutionary cycle is written by hand.
