Evolving Electrical Circuits Through Simulated Evolution

Another application of genetic algorithm to optimize circuit components' values, see here.

The resistor's and NTC thermistor's values must be set up such that the resulting curve (from the circuit equation) matches the curve on the chart below:



At a first glance, it seems a very simple problem, but, as the article observes, it may get hard to solve as the circuit complexity increases.

It remembers me of a tale of a senior student in a class of electrical circuits. The professor put some hard circuit problems to be solved through variable substitutions and so on. There were so many derivatives to be solved and etc. The senior student used a tricky way to solve them:

01. He organized all the equations.

02. He used the Laplace transform to all of them.

03. He put all the parameters on a matrix.

04. He solved all the equations through the Gauss-Jordan method.

I was not there, but some "persons" state that the professor refused his solution!!!

I wonder if that professor is the same guy which once said that 1/2 Ohm is not the same as 0.5 Ohm!!!!
