提出了一种计算化学反应体系跃迁几率的方法,该方法适用于各种速率常数的重复计算。这个想法是基于对偶关系,而不是直接的时间演化的原始反应系统,处理的双重过程。通常,如果改变了原反应体系的速率常数,则应使用新的速率常数再次进行直接时间演化。在另一方面,只有一个解决方案的扩展的对偶过程可以重复使用,以计算各种速率常数的情况下的转移概率。Lotka-Volterra系统的参数估计问题证明了这一想法。
An idea for evaluating transition probabilities in chemical reaction systems is proposed, which is efficient for repeated calculations with various rate constants. The idea is based on duality relations; instead of direct time evolutions of the original reaction system, the dual process is dealt with. Usually, if one changes rate constants of the original reaction system, the direct time evolutions should be performed again, using the new rate constants. On the other hands, only one solution of an extended dual process can be reused to calculate the transition probabilities for various rate constant cases. The idea is demonstrated in a parameter estimation problem for the Lotka-Volterra system.
