We numerically estimate the leading asymptotic behavior of the lengthof the longest increasing subsequence of random walks with step increments following Student's-distribution with parameters in the range. We find that the expected value, withdecreasing fromto. For random walks with a distribution of step increments of finite variance (), this confirms previous observation ofto leading order. We note that this asymptotic behavior (including the subleading term) resembles that of the largest part of random integer partitions under the uniform measure and that, curiously, both random variables seem to follow Gumbel statistics. We also provide more refined estimates for the asymptotic behavior offor random walks with step increments of finite variance.
