The list above just adds evidence to my view. Or is there any way to reach an "accept" state? Why isn't there? Just because the beliefs are too strong. Sure, there must be tight filters. But given the hardness of the question, and considering hardly anybody can make a living working just on this question, which is 'considered unsolvable', how would you accept a sound solution put forward by someone never heard of? Sure, todays crackpots have many options to discredit themselves, but then, is formal proof the only way for this century's Einstein to be appreciated?Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-3722233.post-57059007001559306012009-01-14T22:57:00.000-06:002009-01-14T22:57:00.000-06:00so wait a second, you are telling me that P vs NP ...so wait a second, you are telling me that P vs NP is not do-able ?<BR/><BR/>I believe that P=NP. come on,everyone, would that be such a huge surprise ? <BR/><BR/>how surprising was it when we saw that primes in p.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-3722233.post-12565064675153099382009-01-14T21:23:00.000-06:002009-01-14T21:23:00.000-06:00Actually, private think tanks are not religious at...Actually, private think tanks are not religious at all.
