Mersenne: M39 Text
I tried getting the M39 text file from the Mersenne site, but it keeps saying it is unavailable. Was it taken offline because of heavy traffic?

Mersenne: Cut the Crap!
Can we cut the crap on this list? Better yet, can we have another mailing list that is just announcements? The threads are getting ridiculous. I switched to "digest", but I'm afraid I'll miss the one important announcement among the 100 pieces of less useful email. -- Randy Given [EMAIL PROTECTED] http://members.aol.com/GivenRandy public key at http://members.aol.com/GivenRandy/pgpkey.asc _ Unsubscribe & list info -- http://www.scruz.net/~luke/signup.htm Mersenne Prime FAQ -- http://www.tasam.com/~lrwiman/FAQ-mers
Re: Mersenne: M38 = M6972593
I'm curious - had this already been tested by someone else using the defective v17 software? Randy Given [EMAIL PROTECTED] http://members.aol.com/GivenRandy public key at http://members.aol.com/GivenRandy/pgpkey.asc Unsubscribe & list info -- http://www.scruz.net/~luke/signup.htm

They might find the same sort of bug in Linux in, oh, about 10 years.

I imagine you're referring to the Top Producer list at: http://www.mersenne.org/top.htm With the longer list at: http://www.mersenne.org/top2.htm These are update MANUALLY. Lately it has been about every other week. At the bottom of the list is says when it was "last updated" -- June 06 is the latest I've seen. On the other hand, the list at: http://entropia.com/ips/tops.shtml is updated every hour. However, it only counts time through the IPS. This won't matter since you joined recently, but "old-timers" will have more time on the former lists.

Mersenne: Goodbye...
After the latest two events, I am saying good-bye to Prime95. The latest rumors (?) caused some concern, but then I upgraded to version 18.1 and lost two months of work (it deleted the intermediate files). That did it. Ah, well, it has been fun for two years. I'll probably miss the little red icon -- for a while.

Re: Mersenne: Link from Knuth's Home Page
> So, what the hell's he planning to put in V4? >From Knuth's web page at: http://www-cs-faculty.stanford.edu/~knuth/taocp.html#vol4 his plans for upcoming volumes are: Volume 4 Combinatorial Algorithms, in preparation. Present plans are to publish ``Volume 4'' as three separate subvolumes: Volume 4A, Enumeration and Backtracking 7.1. Boolean techniques (aka bit fiddling) 7.2. Generating all possibilities 7.2.1. Combinatorial generators 7.2.2. Basic backtrack 7.2.3. Efficient backtracking 7.3. Shortest paths Volume 4B, Graph and Network Algorithms 7.4. Graph algorithms 7.4.1. Components and traversal 7.4.2. Special classes of graphs 7.4.3. Expander graphs 7.4.4. Random graphs 7.5. Network algorithms 7.5.1. Distinct representatives 7.5.2. The assignment problem 7.5.3. Network flows 7.5.4. Optimum subtrees 7.5.5. Optimum matching 7.5.6. Optimum orderings 7.6. Independence theory 7.6.1. Independence structures 7.6.2. Efficient matroid algorithms Volume 4C, Optimization and Recursion 7.7. Discrete dynamic programming 7.8. Branch-and-bound techniques 7.9. Herculean tasks (aka NP-hard problems) 7.10. Near-optimization 8. Recursion The material will first appear in beta-test form as fascicles of approximately 128 pages each, issued approximately twice per year beginning in 1999. These fascicles will represent my best attempt to write a comprehensive account, but computer science has grown to the point where I cannot hope to be an authority on all the material covered in these books. Therefore I'll need feedback from readers in order to prepare the official volumes later. The publishers have pledged to make the fascicles available in an inexpensive form, essentially at cost. (Of course, the paper and binding will probably be designed to self- destruct in a few years, so that you will have to buy the real book after it is debugged:-) If all goes as planned, Volumes 4A, 4B, and 4C will be ready in the year 2004. Volume 5 Syntactic Algorithms, in preparation. 9. Lexical scanning (includes also string search and data compression) 10. Parsing techniques Estimated to be ready in 2009. Future plans As I write Volumes 4 and 5, I'll need to refer to topics that belong logically in Volumes 1--3 but weren't invented yet when I wrote those books. Instead of putting such material artificially into Volumes 4 or 5, I'll put it into fascicle form. One of the first such fascicles will be a description of MMIX, a RISC machine that will take the place of MIX. After Volume 5 has been completed, I will revise Volumes 1--3 again to bring them up to date. In particular, the new material for those volumes that has been issued in beta-test fascicles will be incorporated at that time. Then I will publish a ``reader's digest'' edition of Volumes 1--5, condensing the most important material into a single book. And after Volumes 1--5 are done, God willing, I plan to publish Volume 6 (the theory of context-free languages) and Volume 7 (Compiler techniques), but only if the things I want to say about those topics are still relevant and still haven't been said. Volumes 1--5 represent the central core of computer programming for sequential machines; the subjects of Volumes 6 and 7 are important but more specialized.

I forget what timeframe (my books are at work), but it was something like 2006.
