Avida instructions used to coordinate behavior and differentiate.

Within this study, cells have access via mutation to a variety of instructions that enable them to self-replicate, perform functions, coordinate their behavior, and set their propagation status. In this table, we describe several of the instructions that, when executed, enable a cell to coordinate its behavior with other cells (i.e., get_xy, send_message, retrieve_message, broadcast_message), remove itself from consideration as a propagule (i.e., block_propagation), and conditionally execute instructions within its genome (i.e., if_propagule_eligible, if_propagule_ineligible, if_label, if_less, mov_head).
