Title: On optimal algorithms for evaluating monotonic boolean functions
Authors: Y. Breitbart, A. Reiter
PDFCS0031.pdf
Abstract: Boolean functions occur with great frequency in computing. There is hardly a program written without an "if clause" whose arguments must be evaluated. We shall refer to simple predicates of the form "A <relational operator> B" as Boolean variables. The usual practice in writing compilers is to generate code which skips over the evaluation of variables no longer relevant to the value of the expression as a whole (see e.g. [1], section 13.6) but not to attempt any optimization by trying to decide in what order to examine the variables.
