Describe three of the most important limitations of genetic algorithms according to Grupe and Jooste
What will be an ideal response?
• Not all problems can be framed in the mathematical manner that genetic algorithms demand.
• Development of a genetic algorithm and interpretation of the results require an expert who has both the programming and statistical/mathematical skills demanded by the genetic algorithm technology in use.
• It is known that in a few situations the "genes" from a few comparatively highly fit (but not optimal) individuals may come to dominate the population, causing it to converge on a local maximum. When the population has converged, the ability of the genetic algorithm to continue to search for better solutions is effectively eliminated.
• Most genetic algorithms rely on random-number generators that produce different results each time the model runs. Although there is likely to be a high degree of consistency among the runs, they may vary.
• Locating good variables that work for a particular problem is difficult. Obtaining the data to populate the variables is equally demanding.
• Selecting methods by which to evolve the system requires thought and evaluation. If the range of possible solutions is small, a genetic algorithm will converge too quickly on a solution. When evolution proceeds too quickly, thereby altering good solutions too quickly, the results may miss the optimum solution.
