100-step constraint relevant to cognitive level
Einwand
1
#457
An algorithm classical systems execute in millions of time-steps may not be excecutable in 100-steps; thus, the constraint poses a nontrivial challenge to AI by severely limiting the class of cognitively plausible algorithms.
Nick Chater and Mike Oaksford (1990, p.95).

Yes: physical symbol systems can think [3]âThinking is a rule governed manipulation of symbolic representational structures. In humans, symbol systems are instantiated in the brain, but the same symbol systems can also be instantiated in a computer. â59C6EF

The Biological Assumption
The Biological AssumptionâThe brain is the hardware (or wetware) on which the software of the mind is run. Thinking is a symbolic process that is implemented in the neurons of the brain and that can also be implemented in the circuits of a digital computer.â98CE71

Brain has a von Neumann architectureâThree features of Von Neumann architecture also characterise processing in brains: 1) processing is sequential; 2) symbol strings are stored and accessed at specific memory addresses; 3) theres a central processing unit that controls processing.â98CE71

The 100-step constraint
The 100-step constraintâAlogrithms modelling cognitive processes must meet the 100-step constraint for performing complex tasks imposed by the brains timescale. Classical sequential algorithms, which run in millions of time-steps now, seem unlikely to meet the constraint.â98CE71

100-step contraint is directed at implementation level
100-step contraint is directed at implementation levelâThe 100-step constraint simply demonstrates that symbolic processes are implemented differently in the brain than they are on a digital computer. The constraint has to do with trivial implementation details rather than real cognitive processes.âEF597B
