'''API Calculus''' is a program that solves calculus problems using operating systems within a device that solves calculus problems. In 1989, the PI- Calculus was created by [[Robin Milner]] and was very successful throughout the years. The PI Calculus is an extension of the extension of the [http://theory.stanford.edu/~rvg/process.html process algebra CCS], a tool that haswith algebraic languages that are specific to processing and formulating statements.<ref>{{Cite web |title = Process Algebra |url = http://theory.stanford.edu/~rvg/process.html|website = theory.stanford.edu|accessdate access-date= 2015-11-09 |website=theory.stanford.edu}}</ref> The PI CalculusIt provides a formal theory for modeling systems and reasoning about their behaviors.

Milner claimed the detailed characteristics of the API Calculus to be its "Communication Ability, Capacity for Cooperation, Capacity for Reasoning and Learning, Adaptive Behavior, and Trustworthiness."<ref name=":3">{{Cite journal |urllast=Rahimi |first=Shahram |date=2015-10-20 |title=ACVisualizer: A Visualization Tool for Api-Calculus |url=http://www2.cs.siu.edu/~rahimi/papers/17.pdf |title journal= ACVisualizer: A Visualization Tool for Api-Calculus|last =}}{{Dead Rahimi|first = Shahramlink|date =July 2015-10-20|journal2025 = ACVisualizer: A Visualization Tool for Api-Calculus|doi bot=InternetArchiveBot |pmid = |accessfix-date attempted=yes }}</ref> The main purpose of creating this mobile advancement is to better network and communicate with other operators while completing a task. Unfortunately, the API Calculus is not perfect and has faced a problem with its security system. The language has seven features that was created within the device that the [[Π-calculus|PI Calculus]] does not have. Since this program is so advanced by the way the software was created and the different abilities that are offered in the program, it is required to be converted to other programming languages so it can be used on various devices and other computing languages. Although the API Calculus is currently being used by various other programming languages, modifications are still being done since the security on the API Calculus is causing problems to users.

== Features ==

The API Calculus has a wide variety of features including those similar to the [[Π-calculus|PI Calculus]] but it also has new and improved features such as:

* accepts processes to be passed over communication links

* natural grouping of mobile processes is addressed

* features calculus dictionary

* includes milieu - a level of abstraction that is between a single [[mobile agent]]s (combination of computer software and data that is able to transfer from one computer to another independently and still able to work on the most recent computer that data was transferred to) and the device as a whole. It is a very restricted environment that involves zero or many agents or other milieus that work closely together to solve computer based problems.<ref name=":5">{{Cite book|title = Soft Computing Agents: A New Perspective for Dynamic Information Systems|url = https://books.google.com/books?id=jRZxTozuEvgC|publisher = IOS Press|date = 2002-01-01|isbn = 9784274905445|first = Vincenzo|last = Loia}}</ref>

* ability of grouping together [[Host (network)|hosts]] ( a [[Node (networking)|physical node]] - connection point - or software program ) and [[Process (computing)|processes]] ( computer program that is running ) that are similar

* contains different programming languages

* knowledge units

== Verification Strategy ==

The software language used throughout the API Calculus program is translated into two other different languages. It is first translated from API Calculus syntax to [https://wiki.eclipse.org/ATL/User_Guide_-_Overview_of_the_ATL_Language ATEL/ATL], then to [http://www.imagineersystems.com/products/mocha-pro/ MOCHA]. The outcome of the translating module is like the step previously mentioned.<ref name=":1">{{Cite web|title = The First Stage of a System Verification Strategy for API-Calculus.|url = https://www.researchgate.net/publication/221282902_The_First_Stage_of_a_System_Verification_Strategy_for_API-Calculus221282902|website = ResearchGate|accessdateaccess-date = 2015-10-21}}</ref>

== Flaws ==

The only flaw that the API Calculus has is that it doesn't have the ability to not support a security system on mobile devices such as [[laptop computer|laptops]]. The problem is that is any outside source tries to enter the milieu is not allowed to enter because the API Calculus requires proof that is can be a trusted source.
