 Dec15 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. Dec15 comment Basic Math Question for Test @Shahar that was the kind of twist I was talking about. sry - no more comments to you. Dec15 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. Dec15 comment Basic Math Question for Test @crf - funny, your comment after mine time-wise appears before mine. Dec15 comment A contest question on probability or, you phrase the Q right-- not like gibberish. that's what its reading. mathematically. Dec15 comment Basic Math Question for Test what's the passing grade Dec15 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. Oct25 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. Jul7 comment Find the following $\overline{\overline{C}}$ and $\overline{\overline{A\cup C}}$ this a Q of arithmetic Jun17 comment Grouping items into groups with max size define "states", define "items"-- are they identical or different combinations of them count. Jun15 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. Feb23 comment Enumerate solution of $x_{1} + x_{2} + … + x_{r} = n$ There must be some restrictions on domain. otherwise you have infinitely many solutions. Feb8 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. Feb6 comment Uncertaint linear program Never mind polynomial, your problem solves in constant time. Its solution is not any dependent on its parameter values. Feb3 comment Is A∨¬A a tautology when there is a proof (by contradiction)? How is your proof that it is not ? Feb1 comment What kind of algorithm/formula would I need to calculate how many items need to fill requirements? @tsdexter you welcome. glad that helped. Feb1 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. Jan14 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. Jan14 comment Maximum |E| on a given degree-diameter — Reference request @jp26 Thank you for the input. However, I need the reference to cite. Dec24 comment Functional Prime Sums you think you can spare "at least" in your first line ? what does that mean?
