近似最佳解 的英文怎麼說
中文拼音 [jìnsìzuìjiājiě]
近似最佳解
英文
near optimum solution-
The backward error and the structured backward error of the approximate solution are the criteria to judge the stability and the strong stability of the numerical algorithm. condition number is a measure of the sensitivity to the approximate solution for the perturbation of original date
近似解的最佳向後誤差和最佳結構向後誤差的數值分別是判別演算法的穩定性和強穩定性的標準，而條件數則是反映數值問題的解對于該問題數據擾動的敏感程度。Only approximate solutions may be obtained even in the best of circumstances.
即使在最佳的條件下，只能得到近似的解值。On the ground of mpda algorithm and the conclusion of its steady - state performance evaluation, the choice of the detection threshold becomes a matter of optimization under the condition of properly chosen detection model and hypothesis. and the analytic expression of auto - adjusted detection threshold can be deduced via approximate fitting attenuation factor derived from the conclusion of performance estimation. it presents a novel approach for the optimization of detection - tracking system
基於mpda演算法及其穩態性能估計的結論，在適當選擇檢測模型和一定假設條件下，將自適應檢測門限的選擇歸結為一個最優化問題，通過近似擬合性能估計結論中的衰減因子，得到了最佳檢測門限自適應調整的解析表達式，為檢測?跟蹤系統的聯合優化設計提供了一種新思路。
