This paper presents arguments for a balanced approach to modelling and reasoning in an autonomous robotic system. The framework discussed utilizes both declarative and procedural modelling to define the domain, rules, and constraints of the system and also balances the use of deliberative and reactive reasoning during execution.
This paper describes how continuous planning and execution techniques can be used to perform intelligent decision-making for an autonomous Mars rover.
Intelligent behavior for robotic agents requires a careful balance of fast reactions and deliberate consideration of long-term ramifications. The need for this balance is particularly acute in space applications, where hostile environments demand fast reactions, and remote locations dictate careful management of consumables that cannot be replenished.
CLEaR unifies planning and execution processes to increase the responsiveness of a robotic agent operating in these types of environments.

High order multigrid methods based on finite difference discretization of the model problem are examined. The following methods are described: (1) a fixed high order FMG-FAS multigrid algorithm; (2) the high order methods; and (3) results are presented on four problems using each method with the same underlying fixed FMG-FAS algorithm.
