Evolving Circuits

05/25/2007 3:53 AM

I have been looking at Adrian Thompson's work on evolving circuits. Put simply, he has allowed an electrical circuit to 'evolve' using 'genetic algorithms' on an array of 100 (10 x 10) programmable switches, the desired outcome being a circuit to discriminate between two inputs of differing frequency. The final result is a circuit that has no method to 'count', and only uses 32 of it's logic cells! (5 of them where removed as they appeared unconnected to the 'working circuit', but this resulted in the circuit NOT working.) No electrical engineer would design a circuit like this. I cant help but think of all the other applications this could be used for.

This smacks of x files technology. They will probably iimplant this into agent scully.

I forwarded to my EECS pals. I suspect Feynmans ghost is the link between the 5 unconnected and the apparent 'working" cells. Once inside Agent scully, she will become fixated on visiting TUVA.

There could be a clue in the extreme temperature dependency - the circuit clearly uses marginal behaviour of interactions. There's probably something in there about power supply Voltage and impedance and input signal mark-to-space (maybe even amplitude) as well - but I couldn't be bothered to look that much further. For my money, genetic algorithms become more interesting when used to develop robust behaviour (which is possible).

I don't know if batteries qualify as circuits but my batteries evolved to flatteries.

Isn't that de-volving?
