## What is the condition for stability?

The stability condition of a system in its final state is where all the links are | xij | ≈ 1 and xij dxij/dt > 0; either xij increases to 1 or it decreases to − 1. Fig. 5 represents a jammed state, where positive links are within a triad, and negative links are between different triads.

## What is the condition for stability of a system?

## What does sufficient mean in logic?

In logic and mathematics, necessity and sufficiency are terms used to describe a conditional or implicational relationship between two statements.
