Potential of biologically inspired computing

Summary

Introduction

• Overcome the Von Neumann fetch compute store, John was a brilliant Hungarian mathematician who published the earliest paper specifying architecture for digital computing.  It ensured this computing architecture was not patentable.  The architecture has a central processing unit (CPU), random access storage addressable by the CPU and a sequencer.  The architecture encourages a serial software architecture that matches the logic of the sequencer and processing operations on program and data.  Von Neumann, his history, computing architecture and some alternative architecture are reviewed by Melanie Mitchell.

• A central processing unit (CPU) resource supplied with instructions and data to process.  Biology uses a massively distributed processing model which reduces the CPU access bottleneck.  Consequently biological operations do not have to limit competitive invocations, and are less likely to need transactional is an operation which guarantees to complete a defined set of activities or return to the initial state.  For a fee the postal service will ensure that a parcel is delivered to its recipient or will return the parcel to the sender.  To provide the service it may have to undo the act of trying to deliver the parcel with a compensating action.  Since the parcel could be lost or destroyed the service may have to return an equivalent value to the sender.

• Applications are designed to directly implement specific functional requirements.   Maintenance issues and engineering quality strategies including limited connections, reuse, directness and information hiding have promoted
  Bertrand Meyer develops arguments, principles and strategies for creating modular software.  He concludes that abstract data types and inheritence make object orientation a superior methodology for software construction.  Complex adaptive system (CAS) theory suggests agents provide an alternative strategy to the use of objects.

  This page describes the Adaptive Web framework (AWF) test system and the agent programming framework (Smiley) that supports its operation. 
  Example test system statements are included.  To begin a test a test statement is loaded into Smiley while Smiley executes on the Perl interpreter. 
  Part of Smiley's Perl code focused on setting up the infrastructure is included bellow. 
  The setup includes:
  

  • Loading the 'Meta file' specification,
    
  • Initializing the Slipnet, and Workspaces and loading them
    
  • So that the Coderack can be called. 

  The Coderack, which is the focus of a separate page of the Perl frame then schedules and runs the codelets that are invoked by the test statement structures.

• The released application then competes in the marketplace.  Finally selection has an impact on the schematic structures.

• Networks of agents with a shared state that allows them to respond to the signals and initiate further signals and actions.  
• Learned associations of localized signals with general aspects that are important to detect and respond to.  
• An emergent architecture supporting adaptive coordinated deployment of the network of agents.

• Resolve basic aspects of the signal locally so that only highly significant attributes are passed on to other agents in the network. 
• Align detector deployment with local aspects of the environment.
