David Vandevoorde first introduced the acronym SFINAE to describe related programming techniques. [ 1 ] Specifically, when creating a candidate set for overload resolution , some (or all) candidates of that set may be the result of instantiated templates with (potentially deduced) template arguments substituted for the corresponding template ...

ECLAIR – Uses formal methods-based static code analysis techniques such as abstract interpretation and model checking combined with constraint satisfaction techniques to detect or prove the absence of certain run time errors in source code. ESC/Java and ESC/Java2 – Based on Java Modeling Language, an enriched version of Java
Fault detection, isolation, and recovery (FDIR) is a subfield of control engineering which concerns itself with monitoring a system, identifying when a fault has occurred, and pinpointing the type of fault and its location. Two approaches can be distinguished: A direct pattern recognition of sensor readings that indicate a fault and an analysis ...
Furthermore, Chandra and Toueg point out an important fact that the failure detector does not prevent any crashes in the system, even if the crashed program has been suspected previously. The construction of a failure detector is an essential, but a very difficult problem that occurred in the development of the fault-tolerant component in a ...
In this example, we shall encode 14 bits of message with a 3-bit CRC, with a polynomial x 3 + x + 1. The polynomial is written in binary as the coefficients; a 3rd-degree polynomial has 4 coefficients (1x 3 + 0x 2 + 1x + 1). In this case, the coefficients are 1, 0, 1 and 1.
All error-detection and correction schemes 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 that has been determined to be corrupted.
A simple example of this technique could be changing a = a + 1 to a = a – 1. Code mutation produces faults which are very similar to those unintentionally added by programmers. A refinement of code mutation is Code Insertion Fault Injection which adds code, rather than modifying existing code. This is usually done through the use of ...
