    • aggressive Synonyms Aggressive, Offensive. Offensive is the direct opposite to defensive. Offensive warfare is that in which one is quick to give battle, as opportunity offers or can be made, and presses upon the enemy. Aggressive warfare is only secondarily of this sort; primarily it is a warfare prompted by the spirit of encroachment, the desire of conquest, plunder, etc. A war that is thus aggressive is naturally offensive at first, but may lose that character by the vigor of the resistance made; it then ceases to be thought of as aggressive. Hence aggressive has come to be often synonymous with offensive.

In science:

In different regimes, however, aggressive activity functions can cause ‘sluggish mixing’, where the activity process evolves on a much slower time scale than the scaled queue lengths, yielding oscillatory fluid limits that follow random trajectories.
Queue-Based Random-Access Algorithms: Fluid Limits and Stability Issues
In other scenarios, however, the fluid limit reflects that more aggressive activity functions may force the system into inefficient states for extended periods of time and produce instability.
Queue-Based Random-Access Algorithms: Fluid Limits and Stability Issues
We then use the fluid limits to demonstrate the potential instability of aggressive activity functions in Sections IV and V.
Queue-Based Random-Access Algorithms: Fluid Limits and Stability Issues
Results in suggest that more aggressive choices of the functions fi (·) and gi (·), which translate into functions ri (·) that grow faster to infinity, can improve the delay performance.
Queue-Based Random-Access Algorithms: Fluid Limits and Stability Issues
This is a major challenge, and not the real goal of the present paper, since we aim to demonstrate the opposite, namely that more aggressive activity or de-activation functions can cause instability.
