constraint n. 1.強迫,拘束。 2.約束,壓抑,拘泥。 3.強制力。 4.緊張感[狀態(tài)]。 by constraint 勉強,強迫。 feel constraint覺得局促不安,感受壓迫。 show constraint顯得局促。 under [in] constraint 被迫,不得不;被束縛著。
controlling constraint checking by bulk import operations 通過大容量導(dǎo)入操作控制約束檢查
controlling constraints, identities, and triggers with not for replication 使用notforreplication來控制約束、標(biāo)識和觸發(fā)器
5 . the optimal control problems governed by the navier-stokes and a system of parabolic equations with state and control constraints are studies respectively . firstly, the existence of the optimal 5、分別討論由navier-stokes方程和拋物型方程組描述的、具有狀態(tài)與控制約束的最優(yōu)控制問題。
Then, the dynamical programming equations and their associated boundary and final time conditions for the problems of maximization of reliability and of maximization of mean first-passage time are formulated . the optimal control laws are " bang-bang " controls which are derived from the dynamical programming equations and the control constraints 然后利用隨機平均法及隨機動態(tài)規(guī)劃原理導(dǎo)出了以最大可靠性為目標(biāo)的隨機最優(yōu)控制策略,說明了當(dāng)控制力為有界函數(shù)時,隨機最優(yōu)控制即是bang-bang控制。
