In [1], Bernstein proposed a circuit-based implementation of the matrix step of the number field sieve factorization algorithm. These circuits offer an asymptotic cost reduction under the measure " construction cost × run time ". We evaluate the cost of these circuits, in agreement with [1], but argue that compared to previously known methods these circuits(More)
Between the late 1940s and the early 1960s, various American government agencies were involved in attempts to persuade British manufacturers that they could and should improve their productivity. This paper examines the history of such technical assistance programs and in particular tries to assess what they actually achieved. We argue that British managers(More)
