tagname and for meta [meta-tag:tagname]
tagname - it is the same as in the posts. (It probably does not work in rooms which aren't associated with any site. That is most likely explanation why it did not work in the sandbox.)
Let $T = (V , E)$ be a tree with $|V | = n ≥ 2$. How many distinct paths are there (as sub graphs) in $T$? I already have the answer to this question as $(n/2)$. The problem that I'm having is finding anything in the text that helps me to figure out how to arrive at this answer.
The purpose of this question is to link to various old (say $\succeq 1$ year old) closed posts, mostly by no longer active users, most of which are reasonable candidates for deletion, and a few for reopening, while it (in most cases) makes little sense to keep them closed and undeleted. If you h...
How could a free (i.e. free content) alternative for MathSciNet and Zentralblatt be created? Comments Some mathematicians have stopped writing reviews for MathSciNet because they feel their output should be freely available. (The Pricing for MathSciNet is not high, but it is not the point....
Is there a website where i could read/download math reviews appeared in the above Journal? Of course, I guess all the reviews are available on ZBMATH https://zbmath.org/, which is not free for access. Besides, the reviews (before 1990s) on ZBMATH are uploaded as scanned files, not very clear and...
Recently I had a few papers published, and I suppose in response to this, I received a request from Zentralblatt to be a reviewer. They ask some general questions about what I would feel comfortable reviewing, and if I would be willing to receive papers electronically. My concern about just signi...
A fairly wellknown heuristic for TSP that is based on matching is described in the 2003 paper Match twice and stitch: a new TSP tour construction heuristic by Andrew B. Kahng and Sherief Reda. Its basic idea is to generate a vertex-covering collection of even cycles via the union of two edge-disj...
