Barricelli’s numeric organisms Before Core Wars, or the computer game Darwin, just about as soon as a computer was built that could run the program, a rather obscure Italian scientist named Barricelli, did pioneering experiments in digital life. While his work remains largely unknown, it does demonstrate how people have been working on evolving computer …

The dreaded local minimum While talking about various and sundry methods of simulating natural processes like evolution in order to solve problems, the concept of a local minimum has cropped up from time to time. Today, we take a closer look at it, and some of the ways to escape.

Computer ants? Evolution based approaches to generating solutions to complex problems, have some drawbacks. They tend to require a great deal of computing resources, such as processer time and data space. A different approach called “Ant Colony Optimization” requires much less time and number crunching for certain types of problems. The ants use cooperation rather …

Tit for tat, thanks for that In Darwin’s original theory, natural selection was considered to be driven by competition. This presents a problem. If it’s all about survival of the fittest, and out competing all others, why is there so much cooperation in nature? In the 1980/s, a tournament was held in which competitors sent …

Genetic Programming Today we take a look at my favorite evolutionary approach to making computers solve problems. This one has, now and again, produced results that are competitive with what humans can do. Here’s a link to a page about Genetic Programming, including some of the human competitive results. genetic-programming.org Here are a few tutorials …

The genetic algorithm Your DNA has most of the information needed to make you you. The information is encoded through four different chemicals that act as a sort of alphabet, spelling out the language of life. In the 1960/s a similar approach was adopted to solve complex problems. Here’s a tutorial on genetic algorithms and …
Next post in topic A “steampunk computer,” is apparently a style of home or work station. I kind of want one, but… When I think “steampunk” I think actual steam. Or tech on that level, hugely complex, and able to magickly work somehow, instead of falling apart, seizing up and exploding. I think I can …

Evolution strategies In 1963, a couple of students were working in a wind-tunnel, attempting to find a way to figure out how to design surfaces to produce a given airflow. That was, and still is, a difficult problem. There are no simple formula. They decided to see if they could use the power of evolution …
