|If a problem X (decision problem) is known to be NP-Complete, and proven to be reduced to problem Y, can you then say problem Y is NP-Complete?|
| by john in Web Design|
If a problem X (decision problem) is known to be NP-Complete, and proven
to be reduced to problem Y in polynomialtime, can you then say problem Y is
My first thought was, no, problem Y needs to be
shown that it is in NP. But after further thought, if X is reduced to Y, Y
is already considered to be NP-Complete. Now I'm just confused...any help
would be appreciated.

| by AtenRa in Development Tools & Services|
I have a huge problem with using FBO.
I have a multi-pass
display using FBOs and multitexturing. Everything seems to work fine until
the end of first execution of display.
