Dear all, I've just pushed two repositories, they are two complex double oscillators based on two discrete models of the Lotka-Volterra equations.
https://github.com/dariosanfilippo/lotka-volterra_osc_A https://github.com/dariosanfilippo/lotka-volterra_osc_B The main difference is that parameters can be explored in unstable regions as the equations are bounded through tanh() saturators (with adjustable saturating thresholds), and that DC-blockers are deployed within the loops to counterbalance tendencies towards fixed-point attractors. Despite the simplicity of the algorithms, I find the results surprisingly good. I am aware that there is no guard against division by zero in the oscillator B. However, considering that the tanh() function will prevent INF from being generated, aren't the odds of ending up with a NaN due to a 0/0 negligible? Please give it a try and let me know if you like them. Ciao. -- Dr Dario Sanfilippo http://dariosanfilippo.com
