This paper discussed two computationally intensive optimisation algorithms for 0-1 integer programs, namely simulated annealing and branch and bound. It then describes an application specific computing platform designed to accelerate their performance. The paper justifies the general approach and gives details of the algorithms.

This paper revisits one of the first models of analog computation, the General Purpose Analog Computer (GPAC). In particular, we restrict our attention to the improved model presented in [11] and we show that it can be further refined. With this we prove the following: (i) the previous model can be simplified; (ii) it admits extensions having close connections with the class of smooth continuou...

Oil field assimilation needs a complex of facilities and service lines for oil recovery, transportation and refining. It includes wells, collection stations, pipelines, meters, separators, formation pressure maintenance equipment, roads and power lines. Oilfield assimilation depends on the geographical and climatic features of the field, such as the areas under existing buildings, areas taken u...

This paper first tells the rather unusual story of the acquisition of the first scientific computer by the University of Iceland. It then goes on to describe the efforts by the staff of the University Computing Centre to introduce key persons to the use of computers and to teach selected groups of people programming and assist them in using the computer. Finally it lists several applications in...

The MIT J-Machine 2], a massively-parallel computer, is an experiment in providing general-purpose mechanisms for communication, synchronization, and naming that will support a wide variety of parallel models of comptuation. We have developed two experimental dataaow programming systems for the J-Machine. For the rst system, we adapted Papadopoulos' explicit token store 12] to implement static ...

The implementation of what we believe to be the first stored-program digital optical computer is described. The implementation domain consists of lithium niobate directional couplers that are modified to provide optical control and are interconnected with single-mode fiber. The architecture is also the first to employ time-of-flight synchronization. That is, there are no flip-flops used as sync...
