Note—Does Rolling Back Decision Trees Really Require the Independence Axiom?
反驳了LaValle和Wapman的观点，认为扩展式决策树的递归分析在缺乏独立性公理时仍然有效，但将扩展式转化为标准式则不可行。
In a recent article, LaValle and Wapman argue that the recursion analysis of decision trees in extensive form requires the Herstein-Milnor independence axiom. I claim that most extensive form analyses are perfectly proper in the absence of independence, but that the transformation from extensive to normal form is impermissible.
