I didn’t realize this, but using “greater than” and “less than” signs in the SSMV post deleted some lines from the symbolic representations of conflict. That has been fixed, so hopefully those make more sense now. Here’s the important one, which serves as the key for understanding the others:
B ~ G, a Beta and a Gamma come into peaceful contact.
B ~< G, the Gamma initiates conflict.
B >< G, the Beta stands ground and returns fire.
B >> G, the Gamma turns and flees.
B ~> G, the Beta ceases hostilities and extends an offer of peace.
B ~ G, the Gamma accepts and mutual hostility has temporarily ceased.
