The modern mons.on s.s.em cons.s.s.of s.x regional mons.ons.[1]. Thes. regional mons.ons.demons.rate coherently annual variations.of precipitation and atmos.heric circulation patterns. although they have different characteris.ics. Therefore, thes. regional mons.ons.are unified in the context of the global mons.on [1,2], which reflects.the dominant mode of coherent annual variations.of precipitation and atmos.heric circulations.in the tropics.and s.btropics.

The s.rategy evolution proces. of game players.is.highly uncertain due to random emergent s.tuations.and other external dis.urbances. This.paper inves.igates.the is.ue of s.rategy interaction and behavioral decis.on-making among game players.in s.mulated confrontation s.enarios.within a random interference environment. It cons.ders.the pos.ible ris.s.that random dis.urbances.may pos. to the autonomous.decis.on-making of game players. as.well as.the impact of participants. manipulative behaviors.on the s.ate changes.of the players. A nonlinear mathematical model is.es.ablis.ed to des.ribe the s.rategy decis.on-making proces. of the participants.in this.s.enario. s.bs.quently, the s.rategy s.lection interaction relations.ip, s.rategy evolution s.ability, and dynamic decis.on-making proces. of the game players.are inves.igated and verified by s.mulation experiments. The res.lts.s.ow that maneuver-related parameters.and random environmental interference factors.have different effects.on the s.lection and evolutionary s.eed of the agent's.s.rategies. Es.ecially in a highly uncertain environment, even s.all information as.mmetry or mis.alculation may have a s.gnificant impact on decis.on-making. This.als. confirms.the feas.bility and effectivenes. of the method propos.d in the paper, which can better explain the behavioral decis.on-making proces. of the agent in the interaction proces.. This.s.udy provides.feas.bility analys.s.ideas.and theoretical references.for improving multi-agent interactive decis.on-making and the interpretability of the game s.s.em model. © 2024 The Authors.
