  1. Simple genetic algorithm gets local minimization too easily and converges slowly. to solve these problems, adaptive crossover rate that has reverse hyperbolic rel ation with the numbers of iteration is designed, and adaptive mutation rate that has reverse proportion to the distances of parents and reverse exponential relat ion to the numbers of iteration is put forward. the practical simulation results show that the adaptive ga has greater convergence speed and larger probability o f getting the best solution

    簡單遺傳演算法存在著收斂速度慢、易陷入局部極小等缺陷.針對這些缺陷，本文設計出隨相對遺傳代數呈雙曲線下降的自適應交換率，並提出與父串間的相對歐氏距離成反比、隨相對遺傳代數指數下降的自適應變異率.實例驗證表明，具有自適應交換率和變異率的遺傳演算法在收斂速度和獲得全局最優解的概率兩個方面都有很大的提高
  2. Moreover, we ' d like to study the blow - up speed of solution, since there are many results about blow - up speed obtained in elliptic equations, hyperbolic equations but not in schrodinger equations. i ' ve looked through the latest 3 years " " chinese mathematical digest " and " mathematics review " and found there ' s no paper which is mostly concerned at the study of blow - up speed of nls although in some references there are some related results implied in them

    另外，就是想研究解的爆破速度，因為關于解的爆破速度這方面的內容在拋物型方程、雙曲型方程等中都有討論，但筆者查閱了近三年的《中國數學文摘》和《 mathematicsreview 》沒有發現以具體研究nls爆破速度為核心的文章，盡管在其它一些文獻中有一些隱性的結論，所以這是一個較好的課題。
  3. Based on pseudo compressibility, two - dimensional low - speed flows are numerically simulated by solving euler and navier - stokes equations. the pseudo - compressibility term is introduced to the continuity equation of incompressible governing equations, which results in a closed hyperbolic system of equations

    通過在不可壓連續性方程中引入擬壓縮項，使控制方程成為一個封閉且可以沿時間方向推進求解的雙曲型偏微分方程組。
  4. An extended hyperbolic mild - slope equation, which can take such terms as wind input, bottom friction and nonlinearity of wave into account, here has been deduced into a parabolic one in the form of a series of governing equations described with complex amplitude. it became a complete wave model when integrated with corresponding physical and imaginary ( open ) boundaries, and can be solved through the improved crank - nicholson or the well known alternating direction implicit ( adi ) difference method, both of which can accelerate the convergent speed, expand limitation of the mathematical method and improve the quality of the solution

    本文基於綜合考慮底摩阻、風能輸入及非線性影響的推廣雙曲型緩坡方程，將其進行轉換，產生一個演變方程，其復振幅控制方程為拋物線性，並採用adi差分格式、改進的crank - nicholson格式及相應的物理和虛擬（開）邊界條件進行求解，以提高數值模擬的適用性、數值計算的穩定性、收斂速度及精度。
