# Topic: Bk tree

 Category:Trees (structure) - Wikipedia, the free encyclopedia In graph theory, a tree is a graph in which any two points, or vertices, are connected by exactly one path (i.e. An equivalent definition is that a forest is graph of one or more (unconnected) trees (hence the name). Trees are useful abstract structural representations of many different concepts. en.wikipedia.org /wiki/Category:Trees_(structure)   (122 words)

 Binomial Trees, Forests, and Heaps We say that two binomial trees of the same order can be merged by attaching one as a subtree (the rightmost) of the other. If we have labels (keys) on the nodes of a binomial tree, and we impose an ordering property where the parent key is larger than the keys of any of its children, we can construct a heap with a binomial queue. The merging of two binomial trees (of the same index) requires linking one tree as a new child of the root of the other tree. www.cs.rutgers.edu /~kaplan/503/handouts/binomialQ.html   (1682 words)

 Doing the BK thing, Penguin style Merging changes into a tree is called a "pull", and is analagous to 'cvs update'. For example, pushing a change from the testing-and-validation tree would probably be a bad idea, because it will push all changes from vm-hacks, bugfixes, filesys, and personal-hacks trees into the target tree. He could (for example) issue a "bk pull" on vm-2.5 and fs-2.5 trees, to merge their changes, but hold off net-drivers-2.5 because of a change that needs more discussion. lwn.net /2002/0425/a/bk-thing.php3   (1598 words)

 Problem Set 2 A tree is said to be a heap if the value in a node is smaller than the values of the child nodes. The tree on the left is a heap, but the tree on the right is not (since 6 is less than 8). In addition, the heap will contain a tree of rank r for all values r that are the exponents of 2 that correspond to digits 1 in the binary expansion of m. www.cs.cornell.edu /courses/cs312/2005fa/hw/ps2.htm   (2300 words)

 [No title]   (Site not responding. Last check: 2007-10-24) Separate source trees are the means in BitKeeper by which you delineate parallel lines of development, both minor and major. A big part of using BitKeeper is organizing the various trees you have on your local disk, and organizing the flow of changes among those trees, and remote trees. / testing-and-validation Since a "bk push" sends all changes not in the target tree, and since a "bk pull" receives all changes not in the source tree, you want to make sure you are only pushing specific changes to the desired tree, not all changes from "peer parent" trees. www.kernel.org /pub/scm/linux/kernel/bkcvs/linux-2.5/Documentation/BK-usage/bk-kernel-howto.txt,v   (1826 words)

 BK Online: "..tree cutting along Quezon Ave." 1/16/01   (Site not responding. Last check: 2007-10-24) BK witnessed a big mango tree whose limbs were being cut by chainsaws wielded by men from William Uy Construction Corporation on January 11, 2001. The cutting of trees started last January 6 and will be finished bythe 20th of the month, as permitted by ECC (Environmental Compliance Certificate) 98NCRQC139 issued by the DENR. Only 30 trees will be cut, while the 28 that was marked with white paint will be left standing, but uprooted and transfered to another location. www.bwf.org /bk/2001/02/n_05.html   (323 words)

 Kernel Traffic #156 For 4 Mar 2001 Because every tree is a repository, files must be checked out before they will be in their standard places in the source tree. Since a "bk push" sends all changes not in the target tree, and since a "bk pull" receives all changes not in the source tree, you want to make sure you are only pushing specific changes to the desired tree, not all changes from "peer parent" trees. The advantage of allowing him to pull is that you won't have the same data in your BK tree twice, which you would have if you sent him diffs and then pulled the diffs from him. www.kerneltraffic.org /kernel-traffic/kt20020304_156.html   (4790 words)

 BitKeeper - The Scalable Distributed Software Configuration Management System The lack of a bk command to physically remove a file is deliberate, we do not want to encourage this action, since it results in a lack of reproducibility. The most important reason is that if you push to a parent repository used by several other people and you need to hand-merge some changes, the repository will be locked for several minutes and no one else will be able to push to it during that time. you have to be careful not to push the dev tree into bugs, use bk level to prevent this from happening. www.bitkeeper.com /section6.html   (6495 words)

 [No title]   (Site not responding. Last check: 2007-10-24) For BK users, I hope we can get a BK tree that tracks this set up soon, and it should hopefully not be too disruptive either. You either have to keep your tree clean all the time, or you have to generate a new clean tree (usually by exporting patches from your messy one) and throw the messy ones away periodically. That means that in a BK tree, you can't sanely use tags for "private" stuff, like telling somebody else "please sync with this tag". www.kerneltraffic.org /kernel-traffic/kt20050604_309.txt   (4364 words)

 [Bitkeeper-users] BK to CVS conversion tool ?   (Site not responding. Last check: 2007-10-24) I think just exporting the head of the bk tree as one CVS tree would be useful for most of the people most of the time. If people are running parallel lines of development they could export to multiple CVS trees, or (slightly better, but perhaps harder) exporting to branches within a single tree. Probably the most common case for wanting this is to allow moving to BK without disturbing people who are using anoncvs. mail.bitmover.com /pipermail/bitkeeper-users/2002-May/000217.html   (267 words)

 apply the patch - IA64wiki To patch your kernel, you need to have before you start, a kernel tree to be patched, and a patch.

 [No title] We were interested in the binomial heap (a mergeable heap) because Union() is effected in lg n time; in an amortized analysis, Union() is effected in constant time with the Fibonacci Heap, primarily because the "work" of heap maintenance is "put off" until the Extract-Min() operation is needed. With Insert(), we do NOT worry about causing the presence of trees of duplicate size; this situation is remedied during the overhead attached to Extract-Min(). Each tree is visited and a constant number of operations is performed thereupon. ranger.uta.edu /~cook/aa/transcript/ln13-14f   (1372 words)

 bk commits and dates When you pull from one of the trees, like netdev, the commit messages are sent to the bk commit list with the original date stamp of the patch in the netdev tree. For example, if Jeff commited a patch from somebody in his netdev tree 3 weeks ago, and you pull Jeff's tree today, we'll get all the commit messages today, but dated from 3 weeks ago. That means that in my mailing list archive, where my mailer sorts them by date, I can't say, for example, everything that is before the 2.6.11 tag release was in 2.6.11. www.talkaboutsoftware.com /group/linux.kernel/messages/167848.html   (200 words)

 [No title] Repeat 2k times: unite the existing big tree with a singleton, making the singleton the root; do a find on the deepest element in the tree. The following definition of ranks after a union gives strictly increasing ranks: when uniting trees with roots x and y, making x the new parent of y, set the new rank of x to be the maximum of its old rank and one plus the rank of y.
