  • constructive proof — (mathematics)   A proof that something exists that provides an example or a method for actually constructing it. For example, for any pair of finite real numbers n < 0 and p > 0, there exists a real number 0 < k < 1 such that f(k) = (1-k)*n + k*p = 0. A constructive proof would proceed by rearranging the above to derive an equation for k: k = 1/(1-n/p) From this and the constraints on n and p, we can show that 0 < k < 1. A few mathematicians actually reject *all* non-constructive arguments as invalid; this means, for instance, that the law of the excluded middle (either P or not-P must hold, whatever P is) has to go; this makes proof by contradiction invalid. See intuitionistic logic. Constructive proofs are popular in theoretical computer science, both because computer scientists are less given to abstraction than mathematicians and because intuitionistic logic turns out to be an appropriate theoretical treatment of the foundations of computer science.

  • creeping featurism — (jargon)   /kree'ping fee'chr-izm/ (Or "feature creep") A systematic tendency to load more chrome and features onto systems at the expense of whatever elegance they may have possessed when originally designed. "The main problem with BSD Unix has always been creeping featurism." More generally, creeping featurism is the tendency for anything to become more complicated because people keep saying "Gee, it would be even better if it had this feature too". The result is usually a patchwork because it grew one ad-hoc step at a time, rather than being planned. Planning is a lot of work, but it's easy to add just one extra little feature to help someone, and then another, and another, .... When creeping featurism gets out of hand, it's like a cancer. Usually this term is used to describe computer programs, but it could also be said of the federal government, the IRS 1040 form, and new cars. A similar phenomenon sometimes afflicts conscious redesigns; see second-system effect. See also creeping elegance.
  • curvature of space — (in relativity) a property of space near massive bodies in which their gravitational field causes light to travel along curved paths.

  • depth-first search — (algorithm)   A graph search algorithm which extends the current path as far as possible before backtracking to the last choice point and trying the next alternative path. Depth-first search may fail to find a solution if it enters a cycle in the graph. This can be avoided if we never extend a path to a node which it already contains. Opposite of breadth first search. See also iterative deepening.
