This article is a list of standard proofreader's marks used to indicate and correct problems in a text. Marks come in two varieties, abbreviations and abstract symbols. These are usually handwritten on the paper containing the text. Symbols are interleaved in the text, while abbreviations may be placed in a margin with an arrow pointing to the ...
SMS language displayed on a mobile phone screen. Short Message Service ( SMS) language, textism, or textese[ a] is the abbreviated language and slang commonly used in the late 1990s and early 2000s with mobile phone text messaging, and occasionally through Internet -based communication such as email and instant messaging.

Noun phrase. A noun phrase – or NP or nominal (phrase) – is a phrase that usually has a noun or pronoun as its head, and has the same grammatical functions as a noun. [1] Noun phrases are very common cross-linguistically, and they may be the most frequently occurring phrase type. Noun phrases often function as verb subjects and objects, as ...
A nurse practitioner ( NP) is an advanced practice registered nurse and a type of mid-level practitioner. [ 1][ 2] NPs are trained to assess patient needs, order and interpret diagnostic and laboratory tests, diagnose disease, prescribe medications and formulate treatment plans. NP training covers basic disease prevention, coordination of care ...

The P versus NP problem is a major unsolved problem in theoretical computer science. Informally, it asks whether every problem whose solution can be quickly verified can also be quickly solved. Here, quickly means an algorithm that solves the task and runs in polynomial time exists, meaning the task completion time varies as a polynomial ...
NP-hard. Class of problems which are at least as hard as the hardest problems in NP. Problems that are NP-hard do not have to be elements of NP; indeed, they may not even be decidable. NP-complete. Class of decision problems which contains the hardest problems in NP. Each NP-complete problem has to be in NP.
The concept of NP-completeness was introduced in 1971 (see Cook–Levin theorem ), though the term NP-complete was introduced later. At the 1971 STOC conference, there was a fierce debate between the computer scientists about whether NP-complete problems could be solved in polynomial time on a deterministic Turing machine.
