- intel corporation — (company) A US microelectronics manufacturer. They produced the Intel 4004, Intel 8080, Intel 8086, Intel 80186, Intel 80286, Intel 80386, Intel 486 and Pentium microprocessor families as well as many other integrated circuits and personal computer networking and communications products. Gordon Moore and Robert Noyce founded Intel in 1968 to design, manufacture, and market semiconductor computer memory to replace magnetic core memory, the dominant computer memory at that time. Dr. Andrew S. Grove joined Intel soon after its incorporation. Three years later, in 1971, Intel introduced the world's first microprocessor, the Intel 4004. Intel has design, development, production, and administration facilities throughout the western US, Europe and Asia. In 1995 nearly 75% of the world's personal computers use Intel architecture. Annual revenues are rapidly approaching $10 billion. In March, 1994, "Business Week" named Intel one of the top ten American companies in terms of profit, one of the top 15 market value winners, and 16th out of the magazine's top 1,000 companies overall. Intel invested a record $2.9 billion in capital and R&D in 1993, and expects to increase combined spending on these activities to $3.5 billion in 1994. Quarterly sales were $2770M and profits, $640M in Aug 1994. Address: Santa Clara, CA, USA.

- logic programming — (artificial intelligence, programming, language) A declarative, relational style of programming based on first-order logic. The original logic programming language was Prolog. The concept is based on Horn clauses. The programmer writes a "database" of "facts", e.g. wet(water). ("water is wet") and "rules", e.g. mortal(X) :- human(X). ("X is mortal is implied by X is human"). Facts and rules are collectively known as "clauses". The user supplies a "goal" which the system attempts to prove using "resolution" or "backward chaining". This involves matching the current goal against each fact or the left hand side of each rule using "unification". If the goal matches a fact, the goal succeeds; if it matches a rule then the process recurses, taking each sub-goal on the right hand side of the rule as the current goal. If all sub-goals succeed then the rule succeeds. Each time a possible clause is chosen, a "choice point" is created on a stack. If subsequent resolution fails then control eventually returns to the choice point and subsequent clauses are tried. This is known as "backtracking". Clauses may contain logic variables which take on any value necessary to make the fact or the left hand side of the rule match a goal. Unification binds these variables to the corresponding subterms of the goal. Such bindings are associated with the choice point at which the clause was chosen and are undone when backtracking reaches that choice point. The user is informed of the success or failure of his first goal and if it succeeds and contains variables he is told what values of those variables caused it to succeed. He can then ask for alternative solutions.
