The Importance of Parallel Distributed Processing

This is known as combinatorial explosion. It's something like 4.29 times 10 to the 88th in standard and sort of scientific notation. In fact, this is greater than the number of atomic particles that are estimated to exist in the universe. This is in a literal sense bigger than the universe. And what does that mean? That means you cannot do the following. You can't search the whole space. For very, very many problems the problems are combinatorially explosive and therefore you cannot search the space. So even if it's each synaptic connection is exploring a pathway, this is still overwhelming your brain.
