Logic Programming Associates is a company specializing in logic and artificial intelligence software. It was founded in 1980 and is most widely known for its Prolog compilers such as WIN-PROLOG.
LPA was established to exploit research at Imperial College, London into logic programming carried out under the supervision of Prof Robert Kowalski. One of the first implementations made available by LPA was micro-PROLOG which ran on popular 8-bit home computers such as the Sinclair Spectrum and Apple II. This was followed by micro-PROLOG Professional one of the first Prolog implementations for MS-DOS.
In 1989, LPA developed Flex, a Prolog-based expert system toolkit which supported frame-based reasoning with inheritance, rule-based programming and data-driven procedures. Flex included its own English-like Knowledge Specification Language (KSL) for defining knowledge and rules.
In 1992, LPA helped set up the Prolog Vendors Group, a non-profit organization whose aim was to help promote Prolog by making people aware of its usage in industry.
LPA's current compiler is LPA Prolog for Windows, a compiler and development system totally dedicated to the Windows platform.
The current LPA software range comprises an integrated AI toolset which covers various aspects of Artificial Intelligence including Logic Programming, Expert Systems, Knowledge-based Systems, Data Mining, Agents and Case-based reasoning etc.
A recent addition to this range is VisiRule, a graphical tool for developing knowledge-based and decision support systems.
Famous quotes containing the words logic, programming and/or associates:
““... We need the interruption of the night
To ease attention off when overtight,
To break our logic in too long a flight,
And ask us if our premises are right.””
—Robert Frost (1874–1963)
“If there is a price to pay for the privilege of spending the early years of child rearing in the driver’s seat, it is our reluctance, our inability, to tolerate being demoted to the backseat. Spurred by our success in programming our children during the preschool years, we may find it difficult to forgo in later states the level of control that once afforded us so much satisfaction.”
—Melinda M. Marshall (20th century)
“A man should not go where he cannot carry his whole sphere or society with him,Mnot bodily, the whole circle of his friends, but atmospherically. He should preserve in a new company the same attitude of mind and reality of relation, which his daily associates draw him to, else he is shorn of his best beams, and will be an orphan in the merriest club.”
—Ralph Waldo Emerson (1803–1882)
