Figure 1
The monitoring of the transition state showing the punctuated equilibria for the prices p 1 ,p 2 ,p 3 ,p 4 of four selected PUs. Calculated for amoup=0.02, amodn=0.002. We see that price moves as depicted are interrupted by seldom reorganizing events described by Equations 18 and 17(a,b,c,d). Similar bursts of activity are typical for all applications of Bak-Sneppen extremal rules. The time-dependencies are supplemented by the histograms constructed for p1 and p4. We see that distribution of prices comprises large and small peak (e,f). The peak presence has been verified using several independent simulation runs.
