The following text is just a copy of a part of the help information of AFNI's 3dClustsim
"This program is like running AlphaSim once for each '-pthr' value and then
extracting the relevant information from its 'Alpha' output column. ++ One reason for 3dClustSim to be used in place of AlphaSim is that it will
be faster than running AlphaSim multiple times.
++ Another reason is that the resulting table can be stored in an AFNI
dataset's header, and used in the AFNI Clusterize GUI to see estimated
cluster significance (alpha) levels."
Thus, I think their algorithm are same, 3dClustsim is just a streamlined form.

新版会加入一个类似FSL的easythresh的校正。
明白了，非常感谢~！
