Evolutionary Algorithm

Created by TerminalAwareness at 4y

The most basic evolutionary algorithm structure is quite simple:

  1. Create an initial population of solutions (usually at random)
  2. Start iteration (each step is a generation)
    1. Select some pairs to be parents (selection)
    2. Combine pairs of parents to create offspring (recombination)
    3. Perform some mutation(s) on the offspring (mutation)
    4. Select some population members to be replaced by the new offspring based on their fitness to the environment (replacement)
  3. Repeat

The use of evolutionary algorithmsthis kind of programming has roots in the 1950s and has spread through many fields, from engineering, the financial market, chemistry, mathematics, and data mining. Nowadays there’s a great variety in evolutionary algorithms, ranging from simple genetic algorithms (seeking the solution through recombination or mutation) to neuroevolutionary algorithms (where the “genomes” are represented by artificial neural networks). They differ mainly in the amount of populations in use and the operators responsible for introducing change.

It seems possible that with enough computer power we would be able to produce a superintelligence using a sufficiently complex evolutionary algorithm. This method does not require the understanding of intelligence needed to create an AGI nor the scanning equipment needed to create a WBEwhole brain emulation.

More specifically, they are algorithms capable of selecting the most promising, duplicates, recombinesappropriate solution (individual) from a large set (population) through the evaluation of its fitness (how well it adapts to the problem, the environment). Evolution thus takes place through the repetition of such selection.
