[PDF][PDF] Portfolio optimization with conditional value-at-risk objective and constraints
P Krokhmal, J Palmquist, S Uryasev - Journal of risk, 2002 - Citeseer
Recently, a new approach for optimization of Conditional Value-at-Risk (CVaR) was suggested
and tested with several applications. For continuous distributions, CVaR is defined as the …

On finding k-cliques in k-partite graphs
M Mirghorbani, P Krokhmal - Optimization Letters, 2013 - Springer
In this paper, a branch-and-bound algorithm for finding all cliques of size k in a k-partite
graph is proposed that improves upon the method of Grunert et al. (in Comput Oper Res 29(1):13…
