There are 2 other large differences between const and final. Firstly, if you're using const inside a class, you have to declare it as static const rather than just const. Secondly, if you have a const collection, everything inside of that is in const. If you have a final coll...

What would be the difference between /MD and /MT cases.All replies (5)Thursday, May 29, 2008 1:17 PM ✅AnsweredIf you intentionally used /MDd in the Debug config, use /MD in the Release mode configuration. /MD requires installing the side-by-side C run-time libraries on the tar...

In addition, it is possible to allow the search to use a deeper TT cache when available. This may improve the strength, especially for deep searches. Use peek together with -c to enable this. ./2048 -n 4x6patt -i 4x6patt.w -e 10 -d 5p -c 64G peek # peeking the deeper TT ca...

In my understanding the memberfunction size() could be called constexpr in all cases. But there is one case where the behaviour of gcc10 changed compared to gcc9: if the argument is passed by const-ref. I don't understand why this should not be constexpr? Another example: template<...
