It means to search an optimal or approximate optimal free path from start state to target state according to some optimize criterion 它是按照某一優(yōu)化指標規(guī)劃出一條從起始狀態(tài)到目標狀態(tài)的最優(yōu)或者近似最優(yōu)的無碰路徑。
The typical optimizing criterion of triangulation is max - min angle criteria , but it has some restriction when applying in three dimensions . we proposed some amelioration by taking into consider the relationship of points and their neighbors . that can make the triangulation ' s space variation more even , and can reach the surface fairness request 對三角剖分中的典型優(yōu)化準則?最小內(nèi)角最大準則應(yīng)用于三維空間中時的局限性問題提出了改進方法,充分考慮數(shù)據(jù)點與近鄰點的空間關(guān)系,使三角剖分的空間形狀變化盡量均勻,保證了三角剖分網(wǎng)格的光順性要求。
After gone deep into the ideal and substance of pls regression , we had proposed a new optimized criterion and applied monte carlo randomized simulation to figure out the efficiency of the improvement . the calculation proceedings and result interpretations of pls regression were illustrated with two examples in healthy and medicine research 3 、為了克服偏最小二乘回歸存在的不足之處,我們首先推導(dǎo)出與協(xié)方差最大化準則等價的新準則,分析了該準則的幾何意義和物理意義,并在此基礎(chǔ)上,對它加以了一定的改進。
The major contributions of the dissertation are as follows : 1 . it is well known that the multi - value cdma spreading codes can be designed by means of a pair of mirror multi - rate filter - banks based on some optimizing criteria . the dissertation indicates that there exists a theoretical bound in the performance of its circular correlation property , which can be described by an explicit expression . based on this analysis , a criterion of maximizing entropy is proposed to design such codes 研究了基于兩帶鏡像多速率濾波器組來設(shè)計的多值cdma擴展碼的方法,并推導(dǎo)出了基于這種方法設(shè)計的碼序列在循環(huán)相關(guān)特性方面所能達到的極限,以及達到此理論極限時應(yīng)滿足的條件;在此基礎(chǔ)上,提出了一種基于熵最大化準則來產(chǎn)生cdma擴展碼的設(shè)計方法。
