Dont forget your research paper

• Find and read a paper from an acceptable AI
  source
• SIGART (www.acm.org)
• AAAI (American Association of Artificial
  Intelligence)
• Posted to a university website and published in a
  conference or journal dealing with AI
• A paper from one of the AI journals I handed out.
  
• Write a 2-4 page (600-1200 word) response

Review from last time

• When describing and designing agents we need to
  consider the task environment
• Performance Measure
• Environment
• Actuators
• Sensors

Review from last time

• We often describe the environment based on six
  attributes.
• Fully/partially observable
• Deterministic/stochastic
• Episodic/sequential
• Static/dynamic
• Discrete/continuous
• Single agent/multiagent

Environment Types

• The environment type largely determines the agent
  design
• The real world is (of course) partially
  observable, stochastic, sequential, dynamic,
  continuous, multi-agent

RoboCup

• By the year 2050, develop a team of fully
  autonomous humanoid robots that can win against
  the human world soccer champion team.
  (www.robocup.org).
• Develop a PEAS description of the task
  environment for a RoboCup participant.
• Include a thorough classification of the
  environment using RNs six properties of task
  environments.

Agent Types

• Agent architecture program
• Simple reflex agent
• Reflex agent with state
• Goal-based agent
• Utility-based agent
• Learning agent (arguably not a 5th agent but a
  different model of any of the previous agents).

Prep to move onMissionaries and Cannibals

• Three missionaries and three cannibals
• Want to cross a river using one canoe.
• Canoe can hold up to two people.
• Can never be more cannibals than missionaries on
  either side of the river.
• Aim To get all safely across the river without
  any missionaries being eaten.
• Variant 5 and 5 with a canoe that holds 3
