What is on-line logmonitor (Coach)

On-line LogMonitor is a client program that works as an = coach agent as well.
On-line LogMonitor receives information of all agents on the soccer filed from soccer server,
and analyzes the players motion.
It advises an formation to team mate agents  that is evaluated to be effective from several formations.

We used the on-line logmonitor as on-line coach agent at RoboCup99.

Coach Agent

Player Agent

explanation

formation

The coach agents has the following nine formation that team player agents can change their motions.

DEFENSIVE  NARROW	DEFENSIVE	DEFENSIVE WIDE
NORMAL NARROW	NORMAL	NORMAL WIDE
OFFENSIVE NARROW	OFFENSIVE	OFFENSIVE WIDE

data format between coach agent and player agents

The coach agent advises our Kasugabito player agents used in RoboCup 98.
Kasugabito player agent has been programed to move in a specified = range.
The coach agent advice is its normal position and play range to a = player agent.
Items of the data are separated by spaces.

format:
(say kas playerUnum defaultX defaultY maxX maxY minX minY = playerUnum playerUnum defaultX.........)
 

kas          : header indicating team name.

playerUnum   : player's uniform number.

defaultX     : x-coordinate of the player's = normal position.

defaultY     : y-coordinate of the player's = normal position.

maxX         : maximum = x-coordinate of the specified  range.

maxY         : maximum = y-coordinate of the specified  range.

minX         : minimum = x-coordinate of the specified  range.

minY         : minimum = y-coordinate of the specified  range.

strategy of coaching (1): offensive, defensive or normal

• coaching starts after the difference of score is bigger than One.
• if we are advancing, the coach advises more offensive positions.
• otherwise, advises more defensive.
• from second advice
• the coach agent evaluates its own  previous advice.
• number of kicks and scores are used to evaluate the coach agent's = effectiveness over period from the time advised to the time when next advice.
• the effectiveness is calculated as ((kick's number of team mate + gained points * 5) - ( kick's number of opponent players + lost points = *5))/simulation steps of the period.
• when  the effective is minus and there is another formation that is not tried, then try that one, otherwise the advice with the highest = point is used the next one, however

• players are spread along y-axis based on the ball's location of the = previous play_on periods:
• narrow:
• the deviation of the y_coordinate of the  ball position is less = than 1m
       &
• the average position of the y_coordainate is between -5m and 5m.
• wide :
• the deviation of the y_coordinate of the  ball position is more = than 5m

• normal:
• otherwise
