【正文】 器學(xué)習(xí)、數(shù)據(jù)挖掘等各方面. 因此在日常的生活與學(xué)習(xí)中我們要善于用普遍聯(lián)系的哲學(xué)觀去發(fā)現(xiàn)事物、認(rèn)知事物最后找到解決問題的最優(yōu)方法. 局限性遺傳算法作為一種優(yōu)化理論，該文在尋求最優(yōu)解時(shí)，未能對(duì)最優(yōu)解產(chǎn)生的過程進(jìn)行詳細(xì)的描述，只是給出了粗略的介紹, 這是不足的地方. 努力的方向遺傳算法因?yàn)槠鋷缀醪恍枰髥栴}的任何信息，僅需目標(biāo)函數(shù)的信息，就可以得出全局最優(yōu)解，具有非常廣闊的發(fā)展前景. 但是遺傳算法作為一種優(yōu)化理論,其本身就是很復(fù)雜，所以對(duì)任何問題都適用的萬能算法至今仍找不到. 在優(yōu)化理論方面，要注意以下的幾個(gè)方面：(1)對(duì)于對(duì)f(x)的極小值優(yōu)化問題，標(biāo)準(zhǔn)適應(yīng)函數(shù)可定義： ??xnormaif=f； ??x?(?, ] (8) ri= f1?； [0, ) (9)(2)適應(yīng)度函數(shù)的確定適應(yīng)度函數(shù)是用于評(píng)價(jià)各碼串對(duì)問題適應(yīng)程度的準(zhǔn)則. 函數(shù)優(yōu)化問題是直接把函數(shù)本身作為目標(biāo)函數(shù)，對(duì)于復(fù)雜的系統(tǒng)，必須構(gòu)造出恰當(dāng)?shù)哪繕?biāo)函數(shù).(3)確定算法本身的參數(shù)群體的大?。ㄓ址Q群體規(guī)模）n影響遺傳算法的性能. n取得太小，則群體不能提供足夠的信息，算法會(huì)變得很差很難找到問題的解；n取得過大，則算法的計(jì)算量會(huì)增加，使算法的效率下降. 目前常用的群體規(guī)模數(shù)為：n=20～160. 若群體容量較大如：n=100通常取pc=，pm=；若群體容量較小如：n=30通常取pc=，pm=.20參考文獻(xiàn)[1]周勇等. 非數(shù)值并行算法遺傳算法[M]. 北京:科學(xué)出版社,2022:2025.[2]周明, 孫樹棟. 遺傳算法原理及應(yīng)用[M]. 北京: 國(guó)防工業(yè)出版社,1995:1020.[3]徐宗本, 李國(guó). 解全局優(yōu)化問題的仿生類算法(I)[J]. 運(yùn)籌學(xué)雜志,1995,6(12):7072.[4]張文修. 遺傳算法的數(shù)學(xué)基礎(chǔ)[M]. 成都：西安交通大學(xué)出版社,2022:3444.[5]王小平. 遺傳算法理論、應(yīng)用與軟件實(shí)現(xiàn)[M]. 成都：西安交通大學(xué)出版社,2022:5860.[6]張鈴、張鈸. 遺傳算法的機(jī)理研究[J]. 軟件學(xué)報(bào),2022,15(2):57.[7]李敏強(qiáng). 遺傳算法的基本理論與應(yīng)用[M]. 北京: 科學(xué)出版社,2022:8387.[8]吉根林. 遺傳算法研究綜述[J]. 計(jì)算機(jī)應(yīng)用與軟件, 2022,13(5):1113.[9]玄光男，程潤(rùn)傳. 遺傳算法與工程設(shè)計(jì)[M]. 北京: 科學(xué)出版社,2022:6774.[10]馬玉明. 遺傳算法的理論研究綜述[J]. 山東輕工業(yè)學(xué)院學(xué)報(bào),2022:18(3):4653.[11]張麗萍, 柴躍廷. 遺傳算法的現(xiàn)狀及發(fā)展動(dòng)向[J]. 信息與控制,2022,18(5):2317.[12]戴曉暉, 李敏強(qiáng), 寇紀(jì)凇. 遺傳算法理論研究綜述[J]. 控制與決策,2022,16(2):2730.[13]席裕庚, 柴天佑, 惲為民. 遣傳算法綜述[J]. 控制理論與應(yīng)用,1996,13(4):3339.[14]唐穗欣. 標(biāo)準(zhǔn)遺傳算法的原理及算例[J]. 軟件導(dǎo)刊,2022,17(6):2227.[15]俆小龍，王文國(guó). 遺傳算法的原理與應(yīng)用[J]. 沿海企業(yè)與科技,2022,20(3):3438.[16]張文修，梁怡. 遺傳算法的數(shù)學(xué)基礎(chǔ)[M]. 成都：西南交通大學(xué)出版社,2022:104112.[17]潘正君，康立山. 演化計(jì)算[M]. 北京：清華大學(xué)出版社,1998:8489.[18]李敏強(qiáng), 寇紀(jì)凇,林丹,李書全. 遺傳算法的基本理論與應(yīng)用[M]. 北京:科學(xué)出社,2022:7784.[19]孫祥，徐流美. 基礎(chǔ)教程[M]. 北京: 清華大學(xué)出版社,2022:94102.21致　謝轉(zhuǎn)眼間, 我已在曲靖師范學(xué)院度過了四個(gè)年頭. 四年, 一段不短的時(shí)間, 四年的光陰讓我成長(zhǎng), 讓我從青澀走向成熟.此次畢業(yè)論文的每一個(gè)過程都凝結(jié)著劉俊老師的心血, 從選題到答辯的每一步, 都離不開劉老師悉心的指導(dǎo). 劉老師對(duì)我的影響是巨大而深刻的, 這種影響不是一朝的迸發(fā), 而是日積月累的滲透, 在這點(diǎn)滴匯聚中使我逐漸形成正確、成熟的人生觀、價(jià)值觀. 為此, 我常常慶幸于我的幸運(yùn)—有這樣的導(dǎo)師是我本科生生涯的一大幸事! 在此, 我要真誠(chéng)的說聲:“謝謝您, 劉老師!”遺憾的是, 畢業(yè)在即,能夠在劉老師身邊學(xué)習(xí)的日子已屈指可數(shù). 多么希望時(shí)間可以再多些 , 日子可以再長(zhǎng)些, 讓我可以有更多的時(shí)間, 更多的機(jī)會(huì)向劉老師再多學(xué)一點(diǎn). 不過, 在以后的學(xué)習(xí)和生活中我會(huì)謹(jǐn)記劉老師的教導(dǎo)不斷的努力奮斗! 另外, 我還要感謝大學(xué)這四年中辛苦教育我的每位教師 . 是他們的教育, 使我的世界觀、人生觀和價(jià)值觀從幼稚走向成熟！在大學(xué)里, 因?yàn)橛辛死蠋煹囊龑?dǎo),使我的大學(xué)生活不至虛度！最后, 感謝我的朋友, 我的同窗, 感謝你們?cè)谖沂б鈺r(shí)給我鼓勵(lì), 在失落時(shí)給我支持, 感謝你們和我一路走來, 讓我在此過程中倍感溫暖! 感謝我的家人, 沒有你們, 就不會(huì)有今天的我!我一直感恩, 感恩于我可以擁有一個(gè)如此溫馨的家庭, 讓我所有的一切都可以在你們這里得到理解與支持, , 愛我們的家！ 一個(gè)人的成長(zhǎng)絕不是一件孤立的事, 沒有別人的支持與幫助絕不可能辦到. 我感謝可以有這樣一個(gè)空間, 讓我對(duì)所有給予我關(guān)心、幫助的人說聲 “謝謝”! 今后, 我會(huì)繼續(xù)努力, 好好學(xué)習(xí)!好好生活!好好工作!!22附 錄function result=sga(n,a,b,pc,pm,e)%n—群體規(guī)模。endendpopusize=n。x=a+popu2*(ba)/(2.^11)。while wheel=popusize %執(zhí)行轉(zhuǎn)盤式選擇操作if wh(wheel)fitscore(fitone)newpopu(wheel,:)=popu(fitone,:)。newpopu(i+1,:)=popu(i+1,:)。endelsenewpopu(i,:)=popu(i,:)。j=j+1。hold offxlabel(39。t agree with the disciplinary action your employer has taken against you? your employer dismisses you and you think that you have been dismissed unfairly.For more information about dismissal and unfair dismissal, see Dismissal.You can make a claim to an employment tribunal, even if you haven39。s 21 win.Michel Platini, president of European football39。The end of our life, and can meet many things really do?　 　 而窮盡我們的一生，又能遇到多少事情是真正地非做不可？During my childhood, think lucky money and new clothes are necessary for New Year, but as the advance of the age, will be more and more found that those things are optional。s time, your ideas are always special to clear.

However, if you win your case, the tribunal may reduce any pensation awarded to you as a result of your failure to appeal.25Remember that in most cases you must make an application to an employment tribunal within three months of the date when the event you are plaining about happened. If your application is received after this time limit, the tribunal will not usually accept it.If you are worried about how the time limits apply to you, take advice from one of the anisations listed under Further help.Employment tribunals are less formal than some other courts, but it is still a legal process and you will need to give evidence under an oath or affirmation.Most people find making a claim to an employment tribunal challenging. If you are thinking about making a claim to an employment tribunal, you should get help straight away from one of the anisations listed under Further help.If you are being represented by a solicitor at the tribunal, they may ask you to sign an agreement where you pay their fee out of your pensation if you win the case. This is known as a damagesbased agreement.
