  1. In this text, we first do some research on the genetic algorithm about clustering, discuss about the way of coding and the construction of fitness function, analyze the influence that different genetic manipulation do to the effect of cluster algorithm. then analyze and research on the way that select the initial value in the k - means algorithm, we propose a mix clustering algorithm to improve the k - means algorithm by using genetic algorithm. first we use k - learning genetic algorithm to identify the number of the clusters, then use the clustering result of the genetic clustering algorithm as the initial cluster center of k - means clustering. these two steps are finished based on small database which equably sampling from the whole database, now we have known the number of the clusters and initial cluster center, finally we use k - means algorithm to finish the clustering on the whole database. because genetic algorithm search for the best solution by simulating the process of evolution, the most distinct trait of the algorithm is connotative parallelism and the ability to take advantage of the global information, so the algorithm take on strong steadiness, avoid getting into the local

    本文首先對聚類分析的遺傳演算法進行了研究,討論了聚類問題的編碼方式和適應度函數的構造方案與計算方法,分析了不同遺傳操作對聚類演算法的性能和聚類效果的影響意義。然後對k - means演算法中初值的選取方法進行了分析和研究,提出了一種基於遺傳演算法的k - means聚類改進(混合聚類演算法) ,在基於均勻采樣的小樣本集上用k值學習遺傳演算法確定聚類數k ,用遺傳聚類演算法的聚類結果作為k - means聚類的初始聚類中心,最後在已知初始聚類數和初始聚類中心的情況下用k - means演算法對完整數據集進行聚類。由於遺傳演算法是一種通過模擬自然進化過程搜索最優解的方法,其顯著特點是隱含并行性和對全局信息的有效利用的能力,所以新的改進演算法具有較強的穩健性,可避免陷入局部最優,大大提高聚類效果。
  2. She said we should finish by 10 : 00 pm so as not to awaken the neighbors. however we somehow managed to mix up the message so that two days later, at precisely 10 : 00 pm, we began to cu

    不知什麼緣故,我們卻將師父的指示搞混了,糊裡糊塗地就在兩天後的晚上十點整,才開始動工鋸樹,而且連鏈鋸都沒準備。
  3. John farra, a former winter olympian from caribou who trained by running up a ski slope with 80 pounds of mortar mix, won the seventh annual north american wife carrying championship on saturday at sunday river. farra ' s first - place finish earned him and his 110 - pound wife tess her weight in beer and five times her weight in cash, or 550

    第七屆北美年度背老婆錦標賽于上周六在星期日河地區舉行,來自加里本美國緬因州北部的前冬奧會冠軍約翰法拉獲得比賽冠軍,他賽前的訓練是背80磅重的混凝土包跑上一個滑雪坡。
  4. The influence of retarder on the seaing time and ultimate strength of gypsum plaster was investigated in this paper. the experimental results indicate that the effect of single retarder, such as citric acid, is inferior to that of composite retarder which was made of blending citric acid with a few portland cement ( about 0. 5 ?, by weight ). the effect of different water - retention agents, such as polyvinyl alcohol ( pva ), carboxymethyl cellulose ( cmc ), and na - bentonite, etc., was also studied, and the results demonstrate that by means of adding organic and inorganic water - retention agent simultaneously the water - retention of plastering slurry can obviously be improved. the optimal mix proportion of gypsum plaster suitable to finish coat of walls and ceilings of buildings has been got by use of factorial experiment with orthogonal array accounting for interactions between factors each other

    研究了分別以檸檬酸、檸檬酸與普通硅酸鹽水泥復合物作緩凝劑,調節粉刷石膏的凝結時間,並對比2種緩凝體系對石膏抗折、抗壓強度的影響.比較不同保水劑(聚乙烯醇、羧甲基纖維素)以及相同量的保水劑在不同工藝流程下保水效果上的區別.探索了有機保水劑和無機保水劑對粉刷石膏的保水性的影響.結果表明,檸檬酸與普通硅酸鹽水泥的復合緩凝劑比單純的檸檬酸更能有效地延緩建築石膏的凝結,同時建築石膏的抗折、抗壓強度降低幅度減小
