Volume III of Knuth's The Art of Computer Programming (chapter 5, verse 3.2) includes the following table listing the exact minimum number of comparisons required to select the $t$th smallest element from an unsorted set of size $n$, for all $1\le t \le n\le 10$. This table, along with the well-known closed-form expressions $V_1(n) = n-1$ and $V_2(n) = n - 2 + \lceil n/2 \rceil$, represents most of the state of the art as of 1976.
Have any more exact values of $V_t(n)$ been computed in the last 36 years? I'm particularly interested in exact values of $M(n) = V_{\lceil n/2 \rceil}(n)$, the minimum number of comparisons required to compute the median.
As @MarkusBläser points out, Knuth's table seems to already incorporate more recent results from Bill Gasarch, Wayne Kelly, and Bill Pugh (Finding the ith largest of n for small i,n. SIGACT News 27(2):88-96, 1996.)
