question about "merging" two context-free languages (CFL)
Hi, Suppose we have two context-free languages L1 and L2, and they have disjoint alphabet set A1 and A2 (A1 \intersection A2 = \emptyset). Is it possible to "merge" L1 and L2 into a new context-free language L such that 1) the alphabet set A of L is A1 \union A2 2) a sequence of letters W (subset of A... 12 Aug 2010 23:32

P, NP, NP Complete, Intractable in layman terms?

I Guess it's Obvious I also Like to Write [Mythologies of Reason?]
Mythologies of Reason [NO TALGO GO GO GO - JR] First I will speak here of an idea which, as far as I know, has not occurred to anyone. We need a new mythology, however, this mythology must be at the service of the ideas, it must be a mythology of reason. Hegel or Schelling or Hölderlin, “The Oldest System ... 9 Aug 2010 16:48
But Yo, I'm making money, See ["Are Blogs Soviets?"]
Referenced on Unfogged: Are Blogs Soviets? ["What?"] This post is dedicated to my old friend Lisa Kleinman, although I'll understand if she doesn't incorporate the ideas in her body of work. By this point in time the weblog is a mature form of computer-mediated communication, and certain styles of "blog" ha... 9 Aug 2010 16:48
Something Is Possible: "Extensionality is Decidability" [2008]
Extensionality is Decidability Now for a “purer” conjecture I was going to include in the soviet post, but which enthused me enough that I thought I’d save it. In my post “The Triadic Form” I spoke about those old standbys of analytic philosophy of language extensionality and intensionality. A statement where th... 9 Aug 2010 16:48
The Money Part [Civic Networking]
Civic Networking Jeff Rubard In recent comments, I was talking to Union Street‘s Andrew about a longtime hobby-horse of mine, “theoretical republicanism”. A lot of signification is based on composing a view of the world that you want people to find compelling, maybe even over and above your proper purchase on... 9 Aug 2010 15:40
Pole Balancing Applet
Hi Folks, I wrote this little applet : http://tokis-edv-service.de/index.php/beispiele/pole-balancing My program uses Q(0) learning with Dynamic Programming. The state space is continuous, so I partitioned it to make Dynamic Programming possible. Unfortunately it never learns to balance the pole. I think I im... 11 Aug 2010 19:08
3SAT - Short Pigeonhole Refutations
A partitioning solver can produce shorter refutations of the pigeonhole problem than resolution based solvers. Partitioning solvers repeatedly partition SAT instances until a solution is found or all partitions are exhausted. A refutation consists of a list of partitions containing contradictions. Simple Pa... 8 Aug 2010 21:07

A simple template for writing multiprograms; will it work always?
Dear All, I was looking into multiprogramming. After some studies, I thought of a simple template for designing multiprogram code. Many times in multiprogramming, we need to use mutex. generally we choose critical section in our code which if left unprotected, may give erroneous results because of race conditi... 6 Aug 2010 22:34
