'''Isomorphic Algorithms''' (better known as '''ISOs''') were a race of [[program]]s that spontaneously evolved on the [[Grid]], as opposed to being written by [[user]]s. Their existence was considered a miracle by [[Kevin Flynn]]; however, [[Clu 2|Clu]] considered them be an obstruction in his mission to create the perfect system.       

ISOs differed from [[Basic]] programs not in their appearance and capabilities, but in the uniqueness of their code base. They were said to be different due to them not being programmed or controlled by functions, protocols and the need for purpose. While regular programs conform to the rigid structure defined by their users, ISOs had evolved, complete with a genetic code of sorts that even Kevin Flynn could scarcely comprehend. This inner structure of their code would potentially have allowed ISOs to develop beyond the capabilities of regular programs.

== History ==
=== 1984 ===
[[File:Ophelia.png|left|thumb|[[Radia|Ophelia]], the first ISO, emerges from the [[Sea of Simulation]]]]
The first ISO to be born was Ophelia, who later became known as [[Radia]].<ref name=":0">[[TRON: Betrayal]]</ref> Kevin Flynn and Clu discovered her in 1984<ref name=":1">[[TRON: Evolution]]</ref> at the edge of [[Tron City]].<ref name=":0" /> More ISOs were birthed from the [[Grid]], and they astonished Flynn with their abilities.<ref name=":3">[[TRON: Legacy]]</ref>

As the ISO population continuously grew, ISO cities, such [[Arjia City]] and the [[Bostrum Colony]]<ref name=":1" /> were established within the Grid, a district for ISOs was also placed in [[Tron City]].<ref name=":2">[[TRON: Uprising S01E09 Scars, Part 1]]</ref>

=== New system ===
[[File:The Repository.webp|thumb|The Repository, the building that stands center in the society of the secondary Grid made for ISOs.]]
Flynn eventually created a [[New Grid]] and for ISOs to inhabit,<ref>https://www.youtube.com/watch?v=psBwmCb5dQI</ref> he promised to return to this Grid, though he didn't and the system was left to evolve without him. A society is soon forged within this new system and the area that stands center within it is [[The Repository]].<ref>https://store.steampowered.com/app/2109430/Tron_Identity/</ref><ref>[[TRON: Identity]]</ref>

=== 1989 ===
[[File:Isos uprising.png|left|thumb|Multiple ISOs outside of [[Flynn's Arcade]]]]
[[Klax|A]] [[Nord|group]] [[Nord|of]] [[System Monitor|System Monitors]] led by [[Tron]] and [[Dyson]] head to the ISO district of Tron City to stop discriminatory [[Basic|Basics]] from harassing ISOs, though things soon take a turn for the worse when a riot against the ISOs occurs after the death of a single program within the crowd of furious [[Basic|Basics]]. Multiple ISOs were [[Derez|Derezzed]] during the chaos and [[Dyson]], a long time partner of Tron, was disfigured. Crowds of ISOs later surrounded [[Flynn's Arcade]] while waiting for Kevin Flynn to arrive.<ref name=":2" /> Ophelia, now known as [[Radia]], was soon to become a system administrator alongside [[Clu 2]] at the same time, though her installation ceremony was interrupted by a [[Abraxas|viral attack]].<ref name=":1" />

=== The Purge ===
{{Main|Purge}}
[[Clu 2]] later declared war on the ISOs by destroying the [[End of Line Club]], an ISO safe haven. The war became known as the Purge.<ref name=":3" /><ref name=":1" />

==Appearance==
ISOs have a glowing symbol on their arm and some depictions also show other markings on their skin. Their color circuitry is usually white, but the [[Bostrumites]], such as Gibson, modified their circuitry to glow bright green. In the [[Arq Grid]], some ISOs such as the [[Automata]] apparently no longer resembled Users, with some like [[Sierra]] adopting a modified humanoid appearance to make others more comfortable.

The symbol in their arm represents their gender. The female ISO symbol is a hexagon, followed by a "T" shape, while the male ISO symbol replaces the cross with a sideways "V" shape. In ''[[TRON: Evolution - Battle Grids|TRON: Evolution&nbsp;&ndash; Battle Grids]]'' the male/female choice is distinguished by each of these symbols.

==Known ISOs==

*[[Sierra]]
*Unnamed ISO (Named by the player in [[TRON: Evolution - Battle Grids]])

==Trivia==

*The male and female ISO symbols each include a hexagon, a symbol widely used on Kevin Flynn's Grid and possibly symbolic of organic life, since the hexagonal benzene ring is present inside the four building blocks of DNA. The sideways T is the logical symbol for implication; thus the female symbol could be read as implying organic life. The symbols also resemble the traditional symbols for male and female, ♂ and ♀, stylized with a hexagon for the circle, and the protruding arrow and sideways T each detached to stand separately. The symbol for a female ISO can be made using the UNICODE characters for "Software-Function Symbol" (U+2394) and "Assertion" (U+22A6): ⎔⊦. The symbol for a male ISO can be made using the UNIDODE characters for "Software-Function Symbol" (U+2394) and "Medium Right-pointing Angle Bracket Ornament" (U+276D): ⎔❭ . Different fonts will render the characters with different sizing and spacing so try different fonts to make it look perfect.
*A key to intelligence, according to [[Wikipedia:Gödel, Escher, Bach|Godel, Escher, Bach]], is analogy. ISOs' ability to quickly grasp patterns such as analogies, swiftly building knowledge despite lacking preprogrammed directives, may have lent to Kevin Flynn's perception of them as "unimaginably wise".
*Flynn speculated that ISOs differed from Basics through possessing free will, which could not be programmed. However, many Basic programs have been seen to possess initiative, choice, and both will and ability to change, leaving Flynn's criteria questionable. This may also mean that they differ because they cannot be programmed or controlled and require no purpose or function in their systems. 
*ISO has several possible meanings in the context of TRON. [http://en.wiktionary.org/wiki/iso- Iso] is a prefix in the English language derived from Greek meaning "equal". [[wikipedia:ISO_image|ISO]] is also a term in computer science and describes an archived file of an optical disk or disk image. ISO is also a common abbreviation in personals ads that means In Search Of. ISO is so versatile as a word, acronym, and prefix in English and other languages that it accurately reflects the nature of the ISOs in the TRON universe.
