virtual calls overhead / crtp

I'd personally check that by looking at the code gen -- can particularly recommend GCC Explorer: https://gcc.godbolt.org/

<r>`final` does, at least since GCC 4.9: "New type inheritance analysis module improving devirtualization.

C++ 14

<r>Same rules as always, cannot re-declare the variable.It would be equivalent todouble x = 0.0;and thenint x = 0;However, perhaps you can get some of what you want with variadic generic lambdas:<URL url="http://stackoverflow.com/questions/25885893/how-to-create-a-variadic-generic-lambdaNote"><LINK_...

The One-liner Agree/Disagree Thread

<r>Overall, to me the difference between static_if and the above is a bit like the difference between lambdas and function objects -- there are reasons / places where you'd prefer code locality (quick check that doesn't really express a fundamental interface design point on its own) versus less ad-h...

The One-liner Agree/Disagree Thread

<r>QuoteSounds interesting indeed. I'll need to watch it tonight, I'm especially curious about how that "optional" is required. Sound like it's used as a concept check?Yeah, what's really interesting about it is the location of the check -- "static if" can appear right in the middle of the body of a...

The One-liner Agree/Disagree Thread

<r>QuoteYou're right about mentioning OO hierarchies being wrong, it's lacks the ability to handle different hierarchies for multiple context. .. And why would you need a hierarchy anyway? In C++ I like the type-traits which allows you to attached properties to types, non-intrusively, for specific c...

Best book for optimization algorithms

<r>> volatility surface smoothing and trading strategy optimizationAre these non-differentiable problems?If so, then metaheuristics are also worth a shot (most/all are derivative-free).There's plenty of methods here (and plenty of hype, too, unfortunately), the following is a good (no hype) intro: <...
