NOTE FROM MR. SERGEANT ADAMS.

A Note on two theorems by Adams and McGee

Three-valued accounts of conditionals frequently promise (a) to conform to the probabilistic view that conditionals are evaluated by conditional probabilities, and (b) to yield a plausible account of compounds of conditionals. However, McGee (1981) shows that probabilistic validity, the conception of validity most naturally associated with the probabilistic view, cannot be characterized by a fi...

Alignment Elimination from Adams' Grammars

Adams’ extension of parsing expression grammars enables specifying indentation sensitivity using two non-standard grammar constructs — indentation by a binary relation and alignment. This paper proposes a step-by-step transformation of well-formed Adams’ grammars for elimination of the alignment construct from the grammar. The idea that alignment could be avoided was suggested by Adams but no p...

Sergeant X—A Study in Vocational Guidance

was purely a mental one, as he put it, "loss of memory" following upon gassing. He had been gassed during the fall of 1918 but had felt no evil effects until the middle of the following January. His story, as he told it, as he had gleaned it from former companions-inarms and the chaplain of his regiment, was that he had suddenly suffered an entire loss of memory. He had forgotten his name, his ...

Optimal Sherali-Adams Gaps from Pairwise Independence

This work considers the problem of approximating fixed predicate constraint satisfaction problems (MAX k-CSP(P )). We show that if the set of assignments accepted by P contains the support of a balanced pairwise independent distribution over the domain of the inputs, then such a problem on n variables cannot be approximated better than the trivial (random) approximation, even using Ω(n) levels ...
