1. A condition in numerical computing where small errors or perturbations in input data or intermediate calculations are amplified during the computational process, leading to inaccurate or unreliable results.
The numerical method suffered from computational instability when solving the differential equation with a large step size.
O método numérico sofreu com instabilidade computacional ao resolver a equação diferencial com um tamanho de passo grande.
2. The tendency of a computational algorithm or system to produce divergent, oscillating, or erratic behavior due to accumulated rounding errors or algorithmic design flaws.
Engineers had to reformulate their algorithm to avoid computational instability during the iterative process.
Os engenheiros tiveram que reformular seu algoritmo para evitar instabilidade computacional durante o processo iterativo.
This is a specialized technical term primarily used in academia, software engineering, and scientific computing fields in both Brazil and the USA. It reflects the importance of numerical precision in computational science and is a critical concern in fields like climate modeling, financial computing, and engineering simulations. The term is language-agnostic in technical communities.
