  • PROGRAM CRASH signifies that one or more applications died however the rest of the system continues to be working.

Disorganized data on your exhausting drive can sap performance because the computer requires extra time to sift by way of data fragments and dangerous sectors on the drive.

Some issues can solely be solved with algorithms whose execution time grows too shortly in relation to their input to be solved in polynomial time. The Travelling Salesperson Problem is the instance most used to describe intractability. If an issue has an inexpensive time resolution, that’s to say that it may be solved in no more than polynomial time, it’s mentioned to be tractable. Remember that we use Big O notation to characterize time complexity of algorithms. Algorithms of the class O(n2 and n3 are solutions to tractable problems.

The ACube program by Josef Jelinek (RubiksCube.Info) ,talked about in the page on Abstraction, is a good example of this. This program was designed to find optimum and suboptimal solutions to the Rubik’s cube from given states. There is some clarification of the software within the web site.
