算法首先将一个MP给restricted到只带少量的columns,得到RMP。求解RMP,得到dual solution,并将其传递给PP,随后求解PP得到相应的column将其加到RMP中。RMP和PP不断迭代求解直到再也找不到检验数为负的column,那么得到的RMP的最优解也是MP的最优解。如下图所示: image 关于列生成的具体原理,之前已经写过很多详细的文...
In this study, a reliable method for predicting cv is presented based on machine learning (ML). The study considered 11 inherent soil variables, among which the least significant variables are discarded using univariate feature selection technique. Different ML models were developed like the random ...
论文阅读笔记,个人理解,如有错误请指正,感激不尽!该文分类到Machine learning alongside optimization algorithms。 01 Introduction 目前大部分 mixed-integer programming (MIP) solvers 都是基于 branch-and-bound (B&B) 算法。近几年很多新的特性如cutting planes, presolve, heuristics, and advanced branching strate...
在右边,和分别为整数变量和实数变量的下标集合。 02 Learning Branching Decisions 本文并不是提出一个新的branching heuristic,而是使用machine learning通过学习模仿其他分支策略生成的决策去构建一个branching strategy。本文的目标是创造一个效率更高的strong branching的approximation。 2.1 Data Set Genera...
Learned Index Benefits: Machine Learning Based Index Performance Estimation 一、 介绍 索引选择仍然是关系数据库管理系统中最具挑战性的问题之一。本章将会从相关研究背景、研究内容和研究目标来对本文的工作进行总结。 研究背景 对于关系数据库管理系统 (RDBMS),为工作负载创建一组适当的索引可以将查询性能提高几个...

Our machine learning-based restart policy is based on two observations gleaned from our study of LBDs of learnt clauses.译文:我们基于机器学习的重启策略是基于我们对已学习语句的lbd研究中收集到的两种观察结果。 First, we discover that high LBD percentiles can be approximated with z-scores of the ...
Researchers have recently proposed several machine learning-based algorithms for predicting academic achievement. In this paper, Linear Regression algorithm and Random Forest algorithm are used to predict a student's academic achievement. On the basis of confusion matrix, accuracy, precision, recall, and...
