The thesis then studies the emulation modes of routing algorithms with inaccurate network state information , proposes a simulation model based on events for routing algorithms with inaccurate network state information , and develops a routing simulation software r - ns that provides an effective environment for the research of network routing algorithms . randomized routing algorithms based on improved dijkstra and bellman - ford algorithms are proposed for the unicast routing model with inaccurate network state information 本文研究了非精確網絡狀態信息的路由算法模擬仿真方法,提出了非精確網絡狀態信息下基于事件的網絡路由模擬仿真模型,設計并實現了路由模擬仿真軟件rns ,對網絡路由算法的研究提供了很好的支撐環境。

In chapter two , the general model of the optimum investment , consumption and periodical insurance payable at death for life is discussed and its corresponding optimum control question is solved . the optimum strategy can be got through the corresponding hib ( hamilton - jacobi - bellman ) equation . as to the crra ( constant relative risk aversion ) , a sort of utility function , indicatively , the optimum investment process , consumption process and the periodical insurance payable at death for life purchasing process can be gained with the feedback form 第二章討論最優消費、投資、定期人壽死亡保險的一般模型,解決了對應的最優控制問題,最優策略可通過求解hjb ( hamilton一jaeobi一bellman )方程得到,當效用函數為crra (常數相對風險厭惡)類型時,顯式地得到具有反饋形式的最優投資過程、消費過程及定期人壽死亡保險購買過程。

To make it clear , the article use and analyze numerical value cases from bellmum and zadeh . finally in order to work out the value function in all forms and the expected value of optimization in all aspects easily , we take down all the problem existing in multi - stage stochastic decision processes . the solution of optimum is formed and multi - stage stochastic decision tree - table is introduced 為說明問題,本文利用bellman和zadeh [ 1 ]的數值例,應用兩種方法進行分析,最后為了更方便的解出對所有形式的評價函數,及其期望值的最優化解對各種進行的發展,把經過多階段概率決策過程的問題記述下來,構成一個最優解的統一圖表,引入了多段概率決策樹表。

The traditional optimization technique usually combined the fundamental goal of the controller and performance criterion into a single performance index to be minimized by applying technique based on bellman ' s principle of optimality or pontryagin ' s minimum principle . this view of control is designed to obtain the best solution 傳統的優化技術通常把各種控制要求結合而形成一個單獨的性能指標,應用bellman的最優性原理或者龐特里雅金的極小值原理等使其最小化,從而得到問題的一次性最優解。

So far , there have been many types of inequalities of gronwall - bellman - bihari type , including nonlinear inequalities , the inequalities of bihari type , the inequalities on distribution , the inequalities in several variables , discrete inequalities , matrix inequalities and so on Cronwall - bellman - bihari不等式從產生至今已經發展到許多類型,其中包括線性不等式、 bihari型不等式、關于分布的不等式、含多個變量的不等式、離散不等式、矩陣型不等式等等。

In the study of the qualitative theory of differential equations , especially in the study of the stability of differential equations , the estimate of solutions and the boundedness of solutions , gronwall - bellman - bihari inequality can be used as handy tools 在探討微分方程定性理論中,尤其在探討微分方程(組)的穩定性、解的估計及有界性的過程中, gronwall - bellman - bihari不等式是一強有力的工具。

Unfortunately , the problem of finding multicast routing with qos constrained is a np - complete problem . so we can not solve the problem with the classical shortest path first algorithms such as bellman - ford and dijstra 然而研究表明,由于qos組播路由帶有多個qos約束參數,因此qos組播路由問題是一個np完全問題,這使得它與傳統的路由過程不同,難以用經典的最短路徑優先算法求解。

When the bellman does something special for you , such as make a purchase or bring something you have requested to your room , but not room service deliveries , he or she should be tipped $ 2 to $ 3 for every service , at the time it is provided 當行李員為你做了一些特殊的事情,比如替你購物或把你需要的東西送到客房(但不屬于客房服務范疇)等,他應該得到2至3美元的小費

If the registration card is part of a prepared packet , printing the name on the registration card also completes the rooming slip , which is then given to the bellman 如果登記卡是準備好的信息包的一部分,那么把姓名打印在登記卡上,同時也就填好了分房單,交給行李員就行。

Tip him again when you leave with your luggage as he takes it from the bellman and assists you in loading it in your car or into your taxi 當你帶著行李準備離開飯店而門衛從行李員手中接過行李并幫你把它放入你的車子或出租車里時,你還應該付給他小費。

Doormen depending on the amount of luggage , tip $ 1 to $ 2 to the doorman who takes your bags and turns them over to a bellman 給門衛的小費數目取決于行李的多少,為你拿行李并把它遞給行李員的門衛要付給1至2美元的小費。

Depending on the amount of luggage , tip $ 1 to $ 2 to the doorman who takes your bags and turns them over to a bellman 給門衛的小費數目取決于行李的多少,為你拿行李并把它遞給行李員的門衛要付給1至2美元的小費。

Some new results are established in section one , which generalize the important inequalities of bellman - bihari type 本章第一節給出了重要的bellman - bihari型積分不等式的一系列推廣,得到了一些較好的結果。

The inequality of bellman - bihari type is the nonlinear generalization of the noted linear gronwall - bellman inequality Bellman - bihari不等式是著名的gronwall - bellman不等式由線性到非線性的一種推廣形式。

Hello , i ' m li ming , room 1007 . i want to check out now . please prepare my bill and send a bellman to collect my luggage 喂,我是1007房的李明。我想現在就結賬。請準備好我的賬單,派一個行李員來搬行李。

Tip $ 1 a bag but not less than $ 2 to the bellman who carries or delivers your luggage to your room 一個行李包要付1美元的小費,但對于把行李送到客房的行李員要付給2元以上的小費。
