I found very disturbing that there are infinite uncountable problems which are uncomputable.

Was there something you wanted to discuss, or are you just blogging?

>>8541251
Well you should know that a lot of those infinite "not computable" problems are pretty silly.

For example if you have problems A and B, and they are both uncomputable, you can have a different new problem C which ask you tou solve A and later B, and there you go, C is also uncomputable. Later you can do B&A, or A&A&B... and so on.

Infinite problems... well.

Just announcing my frustration to the world :D

but comments are welcome, of course

I want to solve them all!

I think some God (the entity that started the universe simulation we are living) didn't wanted us to know if we are a simulation, so, we can't solve a lot a problems, probably if we could solve them we could determine if we are a simulation

The vast majority of irrational numbers are not computable, perhaps some of the universe constants (like G) are not computable

The interesting part is that there exist classes of algorithms which may compute some undecidable problems.

Consider the advice class P/poly: it can actually solve the unary halting problem!

I think you don't belong here.

I like that idea

>>8541307
where?
>>
>>8541251
'Problems' here are languages, just a set of strings. Most are completley unintresting. Still is pretty cool though

>>8541300
P/1 can solve the unary halting problem because only one TM can be encoded with length n. Even theoretically that's kind of crap
