In contrast to Prolog, which uses backtracking to search for solutions, Curry does not fix a particular search strategy.
If you want to contribute something, please write to www_AT_curry-lang. . In a similar way, one can evaluate nested expressions (where the subexpressions to be replaced are quoted):
There is also another order of evaluation if we replace the arguments of operators from right to left:
In this case, both derivations lead to the same result, a property known as confluence.
Usually, each program contains
some example goals at the end in order to see its
intended application. If
f
{\displaystyle f}
is such a function, we write
f
X
Y
{\displaystyle f\colon X\to Y}

, div 1) is another function: the same as the function inv that returns the multiplicative inverse of its argument, defined by inv(y) =1/y. . Inside there is an anonymous function, receiving a parameter and returning some code. .
However, it seems like Curry has logic programming features similar to Prolog. orgwikiCurry_(programming_language)
Its interesting that Haskell Brooks Curry, a logician after whom this language has (presumably?) been named, has had a programming language named after all three parts of his name.

The notion of continuity makes its appearance in homotopy type theory, where, roughly speaking, two computer programs can be considered to be homotopic, i. Reynolds defined “currying” in a 1972 paper, but did not claim to have coined the term. See what it means to be a Curry Colonel.

yale. Partial application makes it easy to define these functions, for example by creating a function that represents the addition operator with 1 bound as its first argument. Actually, the term curry
does not refer to spices, but to a logician named Haskell Curry (one of
a very small set of people with programming languages named after both their
first and last names). The translation of function happens something like this,function simpleFunction(param1, param2, param3, . given
