The Curriculum Committee on Computer Science (C3S) of the Association for Computing Machinery has been considering curriculum problems for approximately three years. During the early part of this period, a number of informal sessions were held with computer people at various national meetings. In the latter part of this three-year period, the Committee has been formally organized and has made a definite effort to arrive at a concrete suggestions for a curriculum.

Applications of differential equations in general problem solving

A large class of problems leading to digital computer processing can be formulated in terms of the numerical solution of systems of ordinary differential equations. Powerful methods are in existence for the solution of such systems. A good general purpose routine for the solution of such systems furnishes a powerful tool for processing many problems. This is true from the point of view of ease of programming, ease of debugging, and minimization of computer time. A number of examples are discussed in detail.

On reversible subroutines and computers that run backwards

A computer design is described which permits subroutines to be executed backward as well as forward, either with their instructions unchanged or replaced with conjugate instructions. It is shown that using this concept a number of new subroutine types can be developed with rather unusual properties. Since these properties are analogous to certain matrix operations, a arallel nomenclature is suggested for their classification.

Shape the Future of Computing

ACM encourages its members to take a direct hand in shaping the future of the association. There are more ways than ever to get involved.

Get Involved

Communications of the ACM (CACM) is now a fully Open Access publication.

By opening CACM to the world, we hope to increase engagement among the broader computer science community and encourage non-members to discover the rich resources ACM has to offer.
