Our best to provide a comprehensive listing of simulations done in Darwinbots.

Before You Start

You must understand evolution before you can hope to judge the success (or lack thereof) of a simulation. Below are some links to Wikipedia that provide useful knowledge that is generally unknown to the layman on evolution.

• Punctuated Equilibrium - Theory that states that speciation and sudden evolutionary change can only occur in small gene pools. In real life, this tends to be at the edge of what the species finds survivable. These events are rare (hence "punctuated") and are seperated by periods of little change.

Seems to be applicable in Darwinbots since the most striking mutations happen in regions where selection pressures are high.--Endy^chat 17:15, 24 Nov 2005 (MST)

• Muller's Ratchet - Asexual creatures can accumulate "bad" mutations if mutation rates are higher than selective pressures. Eventually this leads to extinction.

Finding the Best

In Darwinbots and in real life there are those individuals who stand apart from the crowd. These are the founder mutants, the lucky few that have dna that provides them a special advantage or interesting behavior.

Finding them though can be a challenge in and of itself. The easiest method is the Crown or King(add link) Button. A single click will highlight the "best" bot in a sim. In the beginning, many bots share virtually identical dna's making this useless. As time progress however only those bots best adapted to the local enviroment will be selected, those that have passed the test of time and are more than fit for futher evolution or indepth dna analysis.

Another method is to find good mutations by watching the sucess of their decendents. With a low enough mutation rate this is fairly easy, as the colors won't vary too rapidly for you to keep up with.

A final method is to simply look for those bots you find to be the most interesting. Perhaps they do an oddball dance, or use ties in an unusual way. Either way providing they can self reproduce and hunt well enough they can be scooped from their crowded native sim and droped into a pristine simulation. These will then further develope their traits, with no boring brethren to worry about. Alternativly their dna can be analyzed to find the source of their behavior, and the behavior incorporated into a more stable version.

Somthing else useful is the population graph provided in DB. Even while you're away with everything sped up, the graph will continue to faithfully display current population dynamics. Upon seeing a large gradual increase, you can take a look and find out how the population growth was made possible.
