•dynamic structure
agents – why?
MultiAgent Systems...
• advanced s/w architecturesdynamic, distributeddecentralised controlsocial, goal-based
• mobility, platform independence• design-time autonomy• reuse
agents – why else?
MultiAgent Systems...
• modelling physiological & biological systems
• modelling social systems
agents also simplify...• concurrency• interfacing s/w units
types of agency
• small scale eg: Netlogoautonomous but limited communication
• generic eg: Jade, Boris (.NET?)communicative & distributed
• BDI eg: 2APL, Goal, Jasonintentional (have plans & goals)
lecture series
• brief look at modelling (Netlogo)• brief look at BDI (2APL)• using Boris to build Java MAS• agent-agent dialog sessions• timers• how to build a Boris
agents – what?
• independent software(?) entities– send & receive messages
like objects but...– distributed– autonomous at design & execution– have their own process thread– tighter encapsulation & interfaces– task oriented
agents – what types?
various types...• web based, brokered• small & mobile• larger scale / intelligent...etc...
Virtual Networks
normally, agents are distributed across• multiple VMs• multi-language VMs• multiple machines
Boris uses network concept based on...• Portals• Routers
tracking activity
