Revision Notes for FRED 7.11


The following features were added in FRED version 7.11.0:

  • The function sample_without_replacement() now uses the Efraimidis P., Spirakis P. (2008) algorithm for weighted sampling without replacement.

  • New Meta agent action: read_agents(<filename>, <global_list_variable>) reads a CSV file with one line per new agent using the format ID,AGE,RACE,SEX. If ID = 0, FRED will generate a unique agent id. New agents are assigned a unique new household that is not added to the simulation region. New agents are not assigned to any other mixing group. The second argument is optional; if a global list-variable is supplied, it is overwritten with the list of IDs of the new agents.

  • New place property clear_schedule = 1 clears the scheduled opening times for a place type, to enable models to redefine schedules for built-in place types.

  • Updated documentation.

  • Bug fixes and efficiency improvements.
