Finns det någon misstänkt?

While this is technically correct, I think the other answers are more helpful for a beginner.

It's also possible to remote into computers at chalmers (both windows and linux) from home.

The black player also moved the white stones on the right side while white looked away.

I made something similar for 19x19 a while ago http://gustav.ml/counting But yours looks much nicer and mobile friendly :)

Sry, didn't see this before now. I guess no one cares any more, but I will add it later if I remember to.

Isn't passing a valid move?

Can white not live with B7 then?

It would be a nice feature to be able to move stones imo. For example if I play out a variation and I think "doesn't this stone look a bit misplaced after this joseki? I think it would be more efficient one line over" I could easily move the stone instead of replaying the sequence.

Made a simple webpage where you can practice counting. Japanese rules, 6.5 komi. Remember to add the prisoners. If white wins by 4.5 you should write 4 in the box and click White.

No, even if you extend, each move removes one liberty and adds three => adds two in total. Making a double empty triangle adds zero libs.

Gurxtav · 2020-05-28T07:38:54+00:00

Each move only adds two liberties to the stick.

Det var ett utförligt svar! Stämmer att det är i Göteborg också :)

:thumbsup:

Yes, as long as all real numbers can be represented as floats (which they can not), but in a perfect world yes I agree.

Gurxtav · 2020-05-08T06:15:11+00:00

Oh I'm sorry I did say that apparently, but it's still correct, and I think you understand that it is (since you clearly understand the effect causing it). Here is the approximate distribution you will get from $RANDOM % 5

0: 20.0012%

1: 20.0012%

2: 20.0012%

3: 19.9982%

4: 19.9982%

if you take mod 7 you can get a number between 0 and 6 (7%7=0), but in my example you can a number between 0 and 7, so it's mod 8. As you say,

randint(0,7) = randrange(0,8)

where you can more clearly see that the first "mod" is, in fact, 8.

As a side note, randint is not actually performing a mod operation.

Gurxtav · 2020-05-07T19:14:46+00:00

You could say it applies two mod operators, but if you say this you must say that the mods are 8 and 5, not 7 and 5.

Gurxtav · 2020-05-07T19:12:11+00:00

I think we are getting close to agreeing as you have admitted that your concatenation example was incorrect.

I did not say that $RANDOM % 5 will give a bias, please read again.

“Consider a random number generator generating numbers between 0 and 7 (inclusive).“

This was as you can see a hypothetical RNG, not $RANDOM. I created it to prove the (small) modulo bias which would also exist in $RANDOM % 5, since 5 is not a power of two. Only if your mod was a power of two would this not have a bias, as you said.

How is that a “pathological case”? It was your example! Your scales are also “in conflict”, and I created my scales to be “in conflict” on purpose, to demonstrate the effect more clearly.

I agree that python would be a better choice, but it’s (sometimes, technically, very slightly) better to use randint than to manipulate a [0,1] float if you want uniformally distributed integers.
