Topological attack simulations

Definition

Topological attack simulations are computational methods used to assess the robustness of biological networks by simulating targeted disruptions to their structure. These simulations help researchers understand how various nodes and connections within a network contribute to its overall stability and functionality. By analyzing the effects of specific attacks on the topology of the network, scientists can identify critical components and predict how failures might impact biological processes.
