thus errors may be introduced during transmission from the source to a receiver. Error detection techniques allow detecting such errors, while error correction enables reconstruction of the original data in many cases.

Error correction is the detection of errors and reconstruction of the original, error-free data. History[edit] The modern development of error-correcting codes in 1947 is due to Richard W. Hamming.[1] A description of Hamming's code appeared in Claude Shannon's A Mathematical Theory of Communication[2] and was quickly generalized by Marcel J. E. Golay.[3] Introduction[edit] The general idea for achieving error detection and correction is to add some redundancy (i.e., some extra data) to a message, which receivers can use to check consistency of the delivered message, and to recover data determined to be corrupted. Error-detection and correction schemes can be either systematic or non-systematic: In a systematic scheme, the transmitter sends the original data, and attaches a fixed number of check bits (or parity data), which are derived from the data bits by some deterministic algorithm. If only error detection is required, a receiver can simply apply the same algorithm to

Get Access Abstract We present a technique for automatically detecting and correcting software bugs. The programmer is required to define a catalog of https://en.wikipedia.org/wiki/Error_detection_and_correction hotspots, syntactic constructs she considered to be error prone (e.g. i < N), together with suitable alternatives (e.g. i < (N + 1) and i < (N - 1)). Given a faulty program, search techniques are then applied to find a combination of alternatives yielding a correct program. The technique is implemented on http://link.springer.com/chapter/10.1007%2F978-3-642-15898-8_5 top of the Java Pathfinder Framework.
