… to be an outcome from some probability space ( Ω , F , P ) , where Ω is a set of random events,
F is a sigma-algebra, and P is a probability measure, which belongs to a linear space X of …

[PDF][PDF] Portfolio optimization with conditional value-at-risk objective and constraints

P Krokhmal, J Palmquist, S Uryasev - Journal of risk, 2002 - Citeseer
… The underlying probability distribution of y in IRm will be assumed for convenience to have
density, which we denote by p(y). This assumption is not critical for the considered approach. …

Higher moment coherent risk measures

PA Krokhmal - 2007 - Taylor & Francis
… In a more general setting one may assume to be a separated locally convex space; for our
purposes it suffices to consider = l p (Ω, f, P), 1 ≤ p ≤ ∞, where the particular value of p shall …

Random assignment problems

PA Krokhmal, PM Pardalos - European Journal of Operational Research, 2009 - Elsevier
… For any p = 2 , … , n , the p-exchange local neighborhood N p of a feasible solution to the
MAP may be defined as the set of solutions obtained from the given one by permuting exactly p

On finding k-cliques in k-partite graphs

M Mirghorbani, P Krokhmal - Optimization Letters, 2013 - Springer
… |V| of nodes in the graph, the graph’s density p, and the total number of k-cliques in the
graph (#CLQ). The density parameter p is used for generation of the graphs, and is equal to the …

Numerical comparison of conditional value-at-risk and conditional drawdown-at-risk approaches: application to hedge funds

P Krokhmal, S Uryasev, G Zrazhevsky - Applications of stochastic …, 2005 - SIAM
29.1 Introduction This paper applies risk management methodologies to the optimization of
a portfolio of hedge funds (fund of funds). We compare risk management techniques based …

Detection of temporal changes in psychophysiological data using statistical process control methods

J Cannon, PA Krokhmal, Y Chen, R Murphey - Computer methods and …, 2012 - Elsevier
… In this study, m out of p principal components p 1 , p 2 ,…,p m were selected such that at
least 80% of the original data's variability was preserved, where the variability attributed to ith …

Certainty equivalent measures of risk

A Vinel, PA Krokhmal - Annals of Operations Research, 2017 - Springer
We study a framework for constructing coherent and convex measures of risk that is inspired
by infimal convolution operator, and which is shown to constitute a new general …

Risk‐averse optimization and resilient network flows

M Eshghali, PA Krokhmal - Networks, 2023 - Wiley Online Library
We propose an approach to constructing metrics of network resilience, where resilience is
understood as the network's amenability to restoring its optimal or near‐optimal operations …
