The network diagram shows labeled nodes and curved connecting lines in various colors. A horizontal color gradient bar at the bottom right is labeled from “2017” to “2021” and shaded from blue to yellow. Some of the yellow nodes present at the center, spanning top to bottom, include “robust optimization,” “portfolio selection models,” “conditional value-at-risk,” and “scenario tree.” Some of the light green nodes present on the bottom left and, on the right, include “costs,” “stochastic systems,” “stochastic models,” “loss aversion,” “risk parity,” “mean-variance,” and “stochastic programming.” Some of the dark green nodes present at the center, spanning top to bottom, include “integer programming,” “portfolio optimization,” “linear programming,” “asset allocation,” “copula,” and “investments.” Some of the teal nodes present at the top center include “optimization,” “financial data processing,” “risk assessment,” “finance,” and “portfolio selection.” Some of the blue-purple nodes present on the left include “dynamic portfolio selection,” “portfolio strategies,” “financial markets,” and “risk measures”.Keywords map.
