RALPH: Meta-level Arbitrator

Description

• The meta-level arbitrator applies meta-reasoning to determine which of the four execution architectures is most likely to produce a best solution
• The arbitrator has meta-knowledge about the performance of the four execution architectures when they are given only limited computation time
• This knowledge, combined with knowledge about the current environment, allows the arbitrator to determine the utility of additional computation; when this utility falls below zero, the arbitrator outputs the current best action
