 Dec 15 comment A contest question on probability a contest Q can't be this vague. your Q fuzzy even in the basic terminology-- "..the set (d1,,,dk) contains..". you mistook the Q or something else missing. Dec 15 comment Basic Math Question for Test @Shahar that was the kind of twist I was talking about. sry - no more comments to you. Dec 15 comment Basic Math Question for Test @Shahar he added the part out of the double quotations-- the rest of his first phrase after mine and this is annoying if nothing else. Dec 15 comment Basic Math Question for Test @crf - funny, your comment after mine time-wise appears before mine. Dec 15 comment A contest question on probability or, you phrase the Q right-- not like gibberish. that's what its reading. mathematically. Dec 15 comment Basic Math Question for Test what's the passing grade Dec 15 comment A contest question on probability The definition of nice integers reads like the following and nothing else: $d_5$ has to be 6-- since it's the only digit greater than 5. When $d_5=6$, $d_4=5$, .., $d_1=2$. And the only nice integer is 234561. something missing here. Oct 25 comment how long does this subroutine and loop take math.stackexchange.com/users/63860/notamathwiz: curious - i'd check this w/the marker. this is the correct answer, and I don't think i'm missing anything. Jul 7 comment Find the following $\overline{\overline{C}}$ and $\overline{\overline{A\cup C}}$ this a Q of arithmetic Jun 17 comment Grouping items into groups with max size define "states", define "items"-- are they identical or different combinations of them count. Jun 15 comment Graph Verification Problem if the two arguments of $f$ are two partitions and not just any two subsets of $V$, you can't verify the edge set for all cases: think about a clique with one edge missing. Feb 23 comment Enumerate solution of $x_{1} + x_{2} + … + x_{r} = n$ There must be some restrictions on domain. otherwise you have infinitely many solutions. Feb 8 comment Combinatorics/Permuation question - Am I overcounting? (Verify my answer) The Q seems to asking for "at most 2 repetitions of a digit". That's any number of digits repeating, but repeating at most twice. 11220045456 is a valid answer, but that's not what your solution is answering. Feb 6 comment Uncertaint linear program Never mind polynomial, your problem solves in constant time. Its solution is not any dependent on its parameter values. Feb 3 comment Is A∨¬A a tautology when there is a proof (by contradiction)? How is your proof that it is not ? Feb 1 comment What kind of algorithm/formula would I need to calculate how many items need to fill requirements? @tsdexter you welcome. glad that helped. Feb 1 comment Problem with slopes. Negative slope means the curve is moving in opposite directions on x- and y-axes -- towards negative on y-axis while the value on x-axis increases. A negative number is negative, doesn't matter where the '-' sign is. Jan 14 comment Maximum |E| on a given degree-diameter — Reference request probably not worked. but it doesn't seem as hard as the lower bound which is solved in part. Jan 14 comment Maximum |E| on a given degree-diameter — Reference request @jp26 Thank you for the input. However, I need the reference to cite. Dec 24 comment Functional Prime Sums you think you can spare "at least" in your first line ? what does that mean?
