I was just starting to get back to coding after a break. This forum got very unfriendly very quick. Maybe Brexit is causing a general increase in grumpiness and a lack of movement. Maybe a chia seed and prune juice pudding would help? if not consult your doctor. While not an OAP like some of you guy...

You can't expect people to maintain 2 systems and two compilers before they post some code. If you want to loosen up maybe the Dandy Warhols are a good band to listen to. Or is it roast beef, Yorkshire pudding and oxo every Sunday.

I didn't put any work into it. Maybe this business between 32 and 64 bit systems again. Who knows. Anyway on my computer it does some mutations, sees if that makes an improvement, if not undoes. I need to decide an optimizer for something I'm doing. I'm not very happy with the code anyway, also I th...

https://github.com/FALCONN-LIB/FFHT The code compiles to 2 objects. In linux you have to use ar to make a libwht.a static library from the objects. wht.bi file: #inclib "wht" declare sub fht_float alias "fht_float" (x as single ptr,ln2size as ulongint) declare sub fht_double ali...

I am almost certain that this is due to libncurses/libtinfo library on my build system being different from the same named shared library on your system. I chose Ubuntu 14.04 as the build system because it's same as what is used on Travis-CI server (what checks the compiler build when we make pull ...

I got this little bit of weirdness when compiling with 1.06 Linux 64 as just released: fbc -O 3 "RNG3.bas" (in directory: /initrd/mnt/dev_save/FB/code) fbc: Symbol `ospeed' has different size in shared object, consider re-linking Compilation finished successfully. The code still works fine.

I wasn't able to use FB for a while with Xenial Linux. I thought that was the end of it. However with the new ScPup64 Linux version the graphics are working again. Okay............

If the uniform random numbers fall on a line between 0 and 1 then you will get less than 0.5 (ie anywhere on the lower half) half the time, less than 0.1 (anywhere on the lower tenth) one over ten of the time, less than 0.01 one over a hundred of the time etc. If you want an equal probability of get...

Behavior trees are often used in more advanced games:

Very technically creative. Maybe you can explore genetic algorithms and neural networks a bit. If I remember correctly you did write some neural network code one time.

There are no bugs in gcc. The bug is people assuming overflows etc are valid c code when they are not. The c compiler knows you will never overflow an integer operation, hence it can assume the carry flag is clear at the end of that operation. Should you do 2's complement arithmetic where overflows ...

Nice RNG algorithm. I must remember it. There is a 128 bit multiply in the AMD 64 instruction set that you can use for fixed point calculations. A random 64 bit number by (n+1) will give a result between 0 and n in the register that contains the high 64 bits of the 128 bit result. Not perfect but ge...

You can do a movd with an ordinary register It's quite slow, about 20 clock cycle I think

The upper bits of a LCG where you use only every second value seems good for uniformity. I also have experimented with using the bswap instruction with LCG. If you generate permutations from a RNG the distribution of those permutations seems like a good test but of course only works on very small se...
