21. It is possible to implement trampolining using higher-order functions in languages that support them, such as C #. 22. Howard published the Fundamental Code Unit ( FCU ) theory, which uses neurophysiological processes to higher order function . 23. Especially, do not use higher order functions without thorough investigation even if they look very promising on simple cases! 24. A combinator is a particular type of higher-order function that may be used in defining functions without using variables. 25. Using GHC-O we get some optimisations, making pattern matching and higher order functions faster than in Clean as well. 26. In the following examples, the higher-order function twice takes a function, and applies the function to some value twice. 27. Sufficient densities will allow, for example, a grocery store, a lower order function , to survive in an isolated location. 28. In case of binary second-order functions such as Cross, Match, and CoGroup, the user can specify one annotation per input. 29. The first-order function is called ( one or ) multiple times with subsets of the input set ( s ). 30. He extended Tersoff's potential function to radical and conjugated hydrocarbon bonds by introducing two additional terms into the bond order function .
