a.M. (Fed. Rep.) Summary. We consider random access machines which read the input integer by integer (not bit by bit). For this computational model we prove a quadratic lower bound for the n-dimensional knapsack problem. For this purpose, we combine a method due to Paul and Simon [1] to apply decisi

โฆ Synopsis
model for a random access computer, is introduced. A unique feature of the model is that the execution time of an instruction is defined in terms of l(n), a function of the size of the numbers manipulated by the instruction. This model has a fixed program, but it is shown that the computing speeds of this model and a stored-program model can differ by no more than a constant factor. It is proved that

We provide general transformations of lower bounds in Valiant's parallel-comparison-decision-tree model to lower bounds in the priority concurrent-read concurrent-write parallel-random-access-machine model. The proofs rely on standard Ramsey-theoretic arguments that simplify the structure of the com
