WebSep 10, 2010 · Optimizing tail-calls in C#. I've got a deeply recursive function that should in theory work well even with large inputs. The problem is at the time of writing I forgot that C# doesn't do tail-call optimization very well, if at all, so I get StackOverflowException s for any complex-enough input. The basic structure of the method is in two large ... WebFeb 22, 2012 · If you can write recursive functions in such a way that the recursive call is the very last thing done (and the function is thus tail-recursive) and the language and compiler/interpreter you are using supports tail recursion, then the recursive function can (usually) be optimised into code that is really iterative, and is as fast as an iterative …

WebStatic methods have nothing to do with tail recursion optimization. All the rules equally apply to instance and static methods, but personally I would never rely on JIT optimizing away my tail calls. Moreover, C# compiler doesn't emit tail call instruction but sometimes it is performed anyway. In short, you never know. WebIt must use recursion. And let's also assume tail recursion is not applied. Tip: One option is still available. We can take the method body from the recursive method X and paste it into the Main method. Info: Obviously, we cannot force the compiler to completely inline a recursive method. Here: This program reduces the calls to the X method by 1. graham\u0027s reserve manly
