我如何在bellmanford算法中获取图的输入?

Bellman-Ford算法是一种用于解决图中单源最短路径问题的动态规划算法。它通过迭代计算每个顶点到起始顶点的最短路径长度,并最终得到起始顶点到其他所有顶点的最短路径长度。

在Bellman-Ford算法中,图的输入通常通过边列表或邻接表进行表示。以下是两种获取图输入的方法:

  1. 边列表(Edge List):将图的边以列表的形式存储,每个元素表示一条边。边列表通常包含三个信息:起始顶点、目标顶点和边的权重。可以通过读取文件或手动创建列表来获取图的输入。下面是一个示例边列表的形式:
  2. 边列表(Edge List):将图的边以列表的形式存储,每个元素表示一条边。边列表通常包含三个信息:起始顶点、目标顶点和边的权重。可以通过读取文件或手动创建列表来获取图的输入。下面是一个示例边列表的形式:
  3. 邻接表(Adjacency List):将每个顶点的邻接边以链表或数组的形式存储。每个顶点都有一个与之相邻的边列表。邻接表可以用字典或数组来表示,其中键或索引表示顶点,值表示与该顶点相邻的边的列表。下面是一个示例邻接表的形式:
  4. 邻接表(Adjacency List):将每个顶点的邻接边以链表或数组的形式存储。每个顶点都有一个与之相邻的边列表。邻接表可以用字典或数组来表示,其中键或索引表示顶点,值表示与该顶点相邻的边的列表。下面是一个示例邻接表的形式:

在使用Bellman-Ford算法时,可以根据实际情况选择使用边列表或邻接表来表示图的输入。根据输入的具体形式,可以使用相应的方法读取和解析图的输入,并将其转换为算法所需的数据结构,如图的邻接矩阵或距离数组,然后进行Bellman-Ford算法的计算。

  • 图论--差分约束--HDU\HDOJ 4109 Instrction Arrangement

    Ali has taken the Computer Organization and Architecture course this term. He learned that there may be dependence between instructions, like WAR (write after read), WAW, RAW. If the distance between two instructions is less than the Safe Distance, it will result in hazard, which may cause wrong result. So we need to design special circuit to eliminate hazard. However the most simple way to solve this problem is to add bubbles (useless operation), which means wasting time to ensure that the distance between two instructions is not smaller than the Safe Distance. The definition of the distance between two instructions is the difference between their beginning times. Now we have many instructions, and we know the dependent relations and Safe Distances between instructions. We also have a very strong CPU with infinite number of cores, so you can run as many instructions as you want simultaneity, and the CPU is so fast that it just cost 1ns to finish any instruction. Your job is to rearrange the instructions so that the CPU can finish all the instructions using minimum time.

    图论--差分约束--POJ 1364 King

    Once, in one kingdom, there was a queen and that queen was expecting a baby. The queen prayed: ``If my child was a son and if only he was a sound king.'' After nine months her child was born, and indeed, she gave birth to a nice son. Unfortunately, as it used to happen in royal families, the son was a little retarded. After many years of study he was able just to add integer numbers and to compare whether the result is greater or less than a given integer number. In addition, the numbers had to be written in a sequence and he was able to sum just continuous subsequences of the sequence. The old king was very unhappy of his son. But he was ready to make everything to enable his son to govern the kingdom after his death. With regards to his son's skills he decided that every problem the king had to decide about had to be presented in a form of a finite sequence of integer numbers and the decision about it would be done by stating an integer constraint (i.e. an upper or lower limit) for the sum of that sequence. In this way there was at least some hope that his son would be able to make some decisions. After the old king died, the young king began to reign. But very soon, a lot of people became very unsatisfied with his decisions and decided to dethrone him. They tried to do it by proving that his decisions were wrong. Therefore some conspirators presented to the young king a set of problems that he had to decide about. The set of problems was in the form of subsequences Si = {aSi, aSi+1, ..., aSi+ni} of a sequence S = {a1, a2, ..., an}. The king thought a minute and then decided, i.e. he set for the sum aSi + aSi+1 + ... + aSi+ni of each subsequence Si an integer constraint ki (i.e. aSi + aSi+1 + ... + aSi+ni < ki or aSi + aSi+1 + ... + aSi+ni > ki resp.) and declared these constraints as his decisions. After a while he realized that some of his decisions were wrong. He could not revoke the declared constraints but trying to save himself he decided to fake the sequence that he was given. He ordered to his

    图论--网络流--费用流--POJ 2156 Minimum Cost

    Dearboy, a goods victualer, now comes to a big problem, and he needs your help. In his sale area there are N shopkeepers (marked from 1 to N) which stocks goods from him.Dearboy has M supply places (marked from 1 to M), each provides K different kinds of goods (marked from 1 to K). Once shopkeepers order goods, Dearboy should arrange which supply place provide how much amount of goods to shopkeepers to cut down the total cost of transport. It's known that the cost to transport one unit goods for different kinds from different supply places to different shopkeepers may be different. Given each supply places' storage of K kinds of goods, N shopkeepers' order of K kinds of goods and the cost to transport goods for different kinds from different supply places to different shopkeepers, you should tell how to arrange the goods supply to minimize the total cost of transport.

    每日论文速递 | [NeurIPS'23 Oral] DPO:Language Model 是一个 Reward Model

    摘要:虽然大规模无监督语言模型(LMs)可以学习广泛的世界知识和一些推理技能,但由于其训练完全不受监督,因此很难实现对其行为的精确控制。获得这种可控性的现有方法通常是通过人类反馈强化学习(RLHF),收集人类对各代模型相对质量的标签,并根据这些偏好对无监督语言模型进行微调。然而,RLHF 是一个复杂且经常不稳定的过程,首先要拟合一个反映人类偏好的奖励模型,然后利用强化学习对大型无监督 LM 进行微调,以最大限度地提高估计奖励,同时不会偏离原始模型太远。在本文中,我们介绍了 RLHF 中奖励模型的一种新参数化方法,它能以封闭形式提取相应的最优策略,使我们只需简单的分类损失就能解决标准的 RLHF 问题。由此产生的算法我们称之为直接偏好优化(DPO),它稳定、性能好、计算量小,在微调过程中无需从 LM 中采样,也无需进行大量的超参数调整。我们的实验表明,DPO 可以对 LM 进行微调,使其与人类偏好保持一致,甚至优于现有方法。值得注意的是,使用 DPO 进行的微调在控制代际情感的能力上超过了基于 PPO 的 RLHF,并且在总结和单轮对话中达到或提高了响应质量,同时在实现和训练方面也要简单得多。
