Undergraduate researcher at Peking University, School of Earth and Space Sciences.

主迭代框架：局部优化+全局优化混合+Tikhonov正则化 Hybrid optimization main iteration framework

算法伪代码

Hybrid optimization pseudocode

Cooling schedule Hybrid optimization cooling schedule $T_0=1$为起始温度，参数c决定了冷却速度，Normally, Slow(c=0.05), Moderate(c=0.8), fast(c=10)

Adam 优化器的超参数一般设置为：$\beta_1=0.9, \beta_2=0.999$
