| 英文摘要 | A generalized Bak-Sneppen model (BS model) of biological evolution with interaction strength theta is introduced in d-dimensional space, where the "nearest neighbors" are chosen among the 2d neighbors of the extremal site, with the probabilities related to the sizes of the fitnesses. Simulations of one- and two-dimensional models are given. For given theta > 0, the model can self-organize to a critical state, and the critical threshold f(c)(theta) decreases as theta increases. The exact gap equation depending on theta is presented, which reduces to the gap equation of BS model as 0 tends to infinity. An exact equation for the critical exponent gamma(theta) is also obtained. Scaling relations are established among the six critical exponents of the avalanches of the model. |
