“…• With/without memory: When a coordination mechanism employs previously calculated activation levels of the behaviors (in addition to the currently calculated activation levels) [34,35,42,44,60,62,63], the method is characterized as with memory. If the system does not preserve previous activation states [11,14,18,23,33,37,38,40,52,55,66,68,77], it is characterized as without memory.…”
