| 31. | This is a primitive recursive function.
|
| 32. | A recursive ascent parser implements an LALR parser using mutually-recursive functions rather than tables.
|
| 33. | In theoretical CS, " recursive function " is basically synonymous with " computable function ".
|
| 34. | As Ben says, in CS, all computable functions are in some sense recursive functions.
|
| 35. | Every primitive recursive function is total recursive, but not all total recursive functions are primitive recursive.
|
| 36. | Every primitive recursive function is total recursive, but not all total recursive functions are primitive recursive.
|
| 37. | The functions that can be programmed in the LOOP programming language are exactly the primitive recursive functions.
|
| 38. | In the late 19th century, Leopold Kronecker formulated notions of computability, defining primitive recursive functions.
|
| 39. | It also supports global and local variables, which permits recursive functions and subroutines to be written.
|
| 40. | But there is no reason, in general, to suppose that such a recursive function exists.
