comment graph avoiding cycle of length 4
I know Jensen's function, but would you please show me how to apply it here? every time I use it on this question I get $m\le \frac{n}{4}(1+2\sqrt{n})$.

comment Identical colored squares in plane
what is geometry of squares?? and BTW for $n=2$, there is an easier way, just consider the leftmost square. squares of the other color satisfy the conditions. I really don't think this needs that much of mathematics because I picked it up from an olympiad paper.....
