This article is a list of notable unsolved problems in computer science. A problem in computer science is considered unsolved when no solution is known or when experts in the field disagree about proposed solutions.
In contrast, no renaming of (x 1 ∨ ¬x 2 ∨ ¬x 3) ∧ (¬x 1 ∨ x 2 ∨ x 3) ∧ ¬x 1 leads to a Horn formula. Checking the existence of such a replacement can be done in linear time; therefore, the satisfiability of such formulae is in P as it can be solved by first performing this replacement and then checking the satisfiability of the ...
These three sets are updated down the access path while keeping the splay operations in check. Another method, semisplaying, modifies the zig-zig case to reduce the amount of restructuring done in all operations. [1] [6] Below there is an implementation of splay trees in C++, which uses pointers to represent each node on the tree.
The case where the distance from A to B is not equal to the distance from B to A is called asymmetric TSP. A practical application of an asymmetric TSP is route optimization using street-level routing (which is made asymmetric by one-way streets, slip-roads, motorways, etc.). The stacker crane problem can be viewed as a special case of the ...
In this case, pFunc is the perturbation function and it is applied to the return value of the function that has been called introducing a fault into the system. Runtime Injection techniques use a software trigger to inject a fault into a running software system. Faults can be injected via a number of physical methods and triggers can be ...
Hadamard's maximal determinant problem, named after Jacques Hadamard, asks for the largest determinant of a matrix with elements equal to 1 or −1. The analogous question for matrices with elements equal to 0 or 1 is equivalent since, as will be shown below, the maximal determinant of a {1,−1} matrix of size n is 2 n−1 times the maximal determinant of a {0,1} matrix of size n−1.
Many high profile cases remain a mystery. Since 2021, Beacon Journal has new light on these cold cases, with the hope of uncovering new leads. Unresolved: Looking back at unsolved cold case ...
Bjarne Stroustrup, who had used Simula for his PhD thesis, created the object-oriented C++. [13] In 1985, Bertrand Meyer also produced the first design of the Eiffel language . Focused on software quality, Eiffel is a purely object-oriented programming language and a notation supporting the entire software lifecycle.
