NP是什么意思？

np的全稱是NP完全問(wèn)題。NP完全問(wèn)題（NP－C問(wèn)題），是世界七大數(shù)學(xué)難題之一。NP的英文全稱是Non－deterministicPolynomial的問(wèn)題，即多項(xiàng)式復(fù)雜程度的非確定性問(wèn)題。簡(jiǎn)單的寫法是NP＝P？，問(wèn)題就在這個(gè)問(wèn)號(hào)上，到底是NP等于P，還是NP不等于P。NP即是多項(xiàng)式復(fù)雜程度的非確定性問(wèn)題。假設(shè)P≠NP，若P＝NP則三類相同。而如果任何一個(gè)NP問(wèn)題都能通過(guò)一個(gè)多項(xiàng)式時(shí)間算法轉(zhuǎn)換為某個(gè)NP問(wèn)題，那么這個(gè)NP問(wèn)題就稱為NP完全問(wèn)題（Non－deterministicPolynomialcompleteproblem）。NP完全問(wèn)題也叫做NPC問(wèn)題。

擴(kuò)展資料：

NP完全問(wèn)題的定義意味著，如果我們得到了一個(gè)NP完全問(wèn)題的多項(xiàng)式確定算法，就說(shuō)明所有的NP問(wèn)題都能夠用一個(gè)確定算法在多項(xiàng)式的時(shí)間內(nèi)解出。因此，P＝NP．換句話說(shuō)，得到了一個(gè)NP完全問(wèn)題的多項(xiàng)式確定性算法可以表明，對(duì)于所有類型的判定問(wèn)題來(lái)說(shuō)，檢驗(yàn)待定解和在多項(xiàng)式時(shí)間內(nèi)求解在復(fù)雜性上沒(méi)有本質(zhì)的差別。這種推論使得大多數(shù)計(jì)算機(jī)科學(xué)家相信P≠NP但是，到目前為止，還沒(méi)有人能從數(shù)學(xué)上證明這一猜想。

動(dòng)態(tài)需求是什么？

動(dòng)態(tài)需求是指消費(fèi)者根據(jù)不同的時(shí)間、地點(diǎn)和情境對(duì)產(chǎn)品或服務(wù)的需求隨時(shí)發(fā)生變化的現(xiàn)象。這種需求的變化可能由季節(jié)、節(jié)假日、突發(fā)事件、市場(chǎng)趨勢(shì)等多種因素引起。
