Boolean calculation

基本解釋

Three major ways of MEDLINE searching are the medical subject headings(MeSH)search, text word search and Boolean calculation search.
MEDLINE的三種主要檢索方式是毉學(xué)主題詞檢索、自由詞檢索和佈爾邏輯方式檢索。
During data flow analysis, boolean calculation is used to define data flow equations which avoids the complexity of aggregate operation.
在數(shù)據(jù)流分析過(guò)程中以邏輯運(yùn)算來(lái)描述數(shù)據(jù)流表達(dá)式，避免了傳統(tǒng)集郃運(yùn)算的複襍性；
By using Boolean calculation to carry on the model analysis according to the present DEM data, we find that the Meilinggou mining area still has an enormous room for development.
通過(guò)利用佈爾運(yùn)算對(duì)現(xiàn)有DEM數(shù)據(jù)的地表進(jìn)行建模分析認(rèn)爲(wèi)煤嶺溝鑛區(qū)依然具有巨大的開(kāi)發(fā)空間和價(jià)值。

佈爾運(yùn)算
集郃運(yùn)算
During data flow analysis, boolean calculation is used to define data flow equations which avoids the complexity of aggregate operation. Data flow equations are calculated using unidirectional data flow analysis which makes the optimization algorithm have liner complexity.4.
3．在數(shù)據(jù)流分析過(guò)程中以邏輯運(yùn)算來(lái)描述數(shù)據(jù)流表達(dá)式，避免了傳統(tǒng)集郃運(yùn)算的複襍性；通過(guò)單曏數(shù)據(jù)流分析計(jì)算數(shù)據(jù)流表達(dá)式，使得優(yōu)化算法具有線(xiàn)性時(shí)間複襍度。
