我们研究了连续时间模拟退火(Xt; t≥0)的收敛速度及其离散化(xk; k = 0,1,…),以逼近给定函数f的全局最优。我们证明了尾部概率P(f(Xt) > min f + δ) (resp。P(f(xk) > min f+δ))随时间衰减多项式(resp。在累积步长中),并提供一个明确的速率作为模型参数的函数。我们的论证应用了最近关于低温下吉布斯测度的函数不等式的发展——艾灵-克莱默斯定律。在离散情况下,得到了保证收敛的步长条件。
We study the convergence rate of continuous-time simulated annealing (Xt; t ≥ 0) and its discretization (xk; k = 0, 1, . . .) for approximating the global optimum of a given function f . We prove that the tail probability P(f(Xt) > min f + δ) (resp. P(f(xk) > min f+δ)) decays polynomial in time (resp. in cumulative step size), and provide an explicit rate as a function of the model parameters. Our argument applies the recent development on functional inequalities for the Gibbs measure at low temperatures – the Eyring-Kramers law. In the discrete setting, we obtain a condition on the step size to ensure the convergence.
