The word FOIL was originally intended solely as a mnemonic for high-school students learning algebra. The term appears in William Betz's 1929 text Algebra for Today, where he states: [2]... first terms, outer terms, inner terms, last terms.
The FOIL algorithm is as follows: Input List of examples and predicate to be learned Output A set of first-order Horn clauses FOIL(Pred, Pos, Neg) Let Pos be the positive examples Let Pred be the predicate to be learned Until Pos is empty do: Let Neg be the negative examples Set Body to empty Call LearnClauseBody Add Pred ← Body to the rule
A word like "first" or "inner" is not meaningful unless you already know that you're supposed to take products of one term from each multiplicand. Indeed, if you didn't know that, FOIL of (a+b)(c+d) might as well mean ab+ad+bc+cd, because the first two things are a and b, and so forth.
This approximation is called the inner solution, and the other is the outer solution, named for their relationship to the transition layer(s). The outer and inner solutions are then combined through a process called "matching" in such a way that an approximate solution for the whole domain is obtained. [3] [4] [5] [6]
Usha and JD share three children: Ewan Blaine, 7, Vivek, 4, and Mirabel Rose, 3. Ewan Blaine was born in June 2017. Vivek was born in February 2020.
The jar is charged by an electrostatic generator, or other source of electric charge, connected to the inner electrode while the outer foil is grounded. The inner and outer surfaces of the jar store equal but opposite charges. [30] The original form of the device is just a glass bottle partially filled with water, with a metal wire passing ...
So NASA’s scientists wrapped the cables in a whole lot of aluminum foil and found that in 1979 Voyager 1 had safely swung past Jupiter and would continue on its legendary journey.
Japan won its second fencing gold medal of the Paris Olympics by beating Italy 45-36 in the last bout of the Games in the men's team foil final Sunday. Japan's alternate, Yudai Nagano, came in for ...
