摘要：
This paper describes the details of the simulated annealing algorithm proposed to estimate the parameters of multiple current dipoles using biomagnetic data. The paper discusses the effects of the choices of such numerical conditions as the amount of estimate transitions, the equilibrium criterion, and the temperature decrement on the algorithm's performance. Incorrect results from the computer simulation obtained with inappropriate choices of such conditions are presented. The verification of a near-optimum convergence by reheating and reannealing is demonstrated. A modification of this algorithm is proposed for implementation by parallel computer, and the validity of this parallel algorithm is also demonstrated by computer simulation.
