Figure 2
The network diagram shows densely interconnected nodes, grouped into five clusters by color. Five labeled arrows point to different parts of the network and are labeled “Cluster 1,” “Cluster 2,” “Cluster 3,” “Cluster 4,” and “Cluster 5.” Cluster 1 points to a group of red nodes on the top right, including the nodes labeled “portfolio selection,” “robust optimization,” “optimization,” “integer programming,” “costs,” “finance,” “risk assessment,” and “loss aversion.” Cluster 2 points to green nodes on the bottom left, including “stochastic models,” “stochastic systems,” “stochastic programming,” “scenario tree,” “linear programming,” “conditional value-at-risk,” and “risk parity.” Cluster 3 is labeled for blue nodes on the left, which include “investments,” “portfolio strategies,” “financial data processing,” “financial markets,” “dynamic portfolio selection,” and “portfolio selection models.” Cluster 4 is marked near yellow nodes on the right, which include terms such as “mean-variance,” “value-at-risk,” and “portfolio optimization.” Cluster 5 indicates the purple nodes on the bottom right, labeled “asset allocation,” “copula,” and “risk measures”.Network visualization.
