In bergant/nlexperiment: Exploration of NetLogo Agent Based Models

Exploration of NetLogo (Wilensky 1999) agent based models.

A tool for NetLogo experiment definition, exploring simulation results and model optimization. Makes it easy to turn the cycle of experiment definition, data analysis, visualisations and parameter fitting into readable and reproducible documents.

RNetLogo package (Thiele 2014) is used as an interface to NetLogo environment.

Functions in nlexperiment assume the following steps:

Define NetLogo experiment object with parameter sets, measures and simulation options (see nl_experiment function).
Run experiment (see nl_run). The result of running an experiment keeps original experiment definition along with the simulation results and makes the process of model analysis more concise and reproducible. To run the simulation in parallel working processes use the parallel attribute in nl_run function.
Analyse and present results of simulation(s). See nl_get_result for getting different data from the result and nl_show_step, nl_show_patches for pre-defined plots.
When additional questions pop out, changes to experiment will be needed. Refine the original definition of the experiment by changing only parameter sets (nl_set_param_values), set different measures (nl_set_measures) or set other simulation options (nl_set_run_options).

The ideas and principles of NetLogo experiment definition is taken from the NetLogo's Behavior Space tool http://ccl.northwestern.edu/netlogo/docs/behaviorspace.html and BehaviorSearch tool http://www.behaviorsearch.org/
