Hence, the Small Set Expansion Hypothesis, which postulates that SSE is hard to approximate, is a stronger (but closely related) assumption than the Unique Game Conjecture. [25] Some approximation problems are known to be SSE-hard [26] (i.e. at least as hard as approximating SSE).
A simple example of an NP-hard problem is the subset sum problem. Informally, if H is NP-hard, then it is at least as difficult to solve as the problems in NP. However, the opposite direction is not true: some problems are undecidable, and therefore even more difficult to solve than all problems in NP, but they are probably not NP-hard (unless ...
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.
Steven Pinker wrote in 1994 that "the main lesson of thirty-five years of AI research is that the hard problems are easy and the easy problems are hard". [ 3 ] By the 2020s, in accordance with Moore's law , computers were hundreds of millions of times faster than in the 1970s, and the additional computer power was finally sufficient to begin to ...
Tick, atomic unit, equivalent to 100 nanoseconds, used to define system time in computing; Tick (software), a time tracking software; Tick, a delay of 1/18 seconds in IPX routing (IPX Rip) used instead of hop counting [clarification needed] Tick, a computer instruction cycle, which is, in some operating systems, a unit countable by software
Also simply application or app. Computer software designed to perform a group of coordinated functions, tasks, or activities for the benefit of the user. Common examples of applications include word processors, spreadsheets, accounting applications, web browsers, media players, aeronautical flight simulators, console games, and photo editors. This contrasts with system software, which is ...
In computer science and computer programming, system time represents a computer system's notion of the passage of time. In this sense, time also includes the passing of days on the calendar . System time is measured by a system clock , which is typically implemented as a simple count of the number of ticks that have transpired since some ...
The Ixodidae are the family of hard ticks or scale ticks, [1] one of the three families of ticks, consisting of over 700 species. They are known as 'hard ticks' because they have a scutum or hard shield, which the other major family of ticks, the 'soft ticks' ( Argasidae ), lack.
