应用背景基于Qt的数据管理系统，对Qt的数据库进行了一次应用，对于Qt初学者学习开发数据库等技术有较强学习价值。。。。。。。关键技术setFixedSize(750, 500); ui->stackedWidget->setCurrentIndex(0); QSqlQueryModel *typeModel = new QSqlQueryModel(this); typeModel->setQuery("select name from type"); ui->sellTypeComboBox->setModel(typeModel); QSplitter *splitter = new QSplitter(ui->managePage); splitter->resize(700, 360); splitter->move(0, 50); splitter->addWidget(ui->toolBox); splitter->addWidget(ui->dailyList); splitter->setStretchFactor(0, 1); splitter->setStretchFactor(1, 1); on_sellCancelBtn_clicked(); showDailyList(); ui->typeComboBox->setModel(typeModel); createChartModelView();

本人新研究的一个MOPSO（多目标粒子群算法），用于各种优化计算，C++编译，非常好用， 何选择带领者呢？ MOPSO在存档中选择一个粒子跟随。如何选择呢？根据网格划分，假设每个网格中粒子数个，i代表第几个网格。该网格中的粒子被选择的概率为，即粒子越拥挤，则选择的概率越低。这是为了保证能够对未知的区域进行探索。 请点击左侧文件开始预览 ！预览只提供20%的代码片段，完整代码需下载后查看 加载中 侵权举报

用C语言实现进程调度－操作系统课程设计设计思想： “最高优先数优先”调度算法的基本思想是把cpu分配给就绪队列中优先数最高的进程。采用动态优先数，即优先数在创建进程时给定一个初始值，当进程获得一次cpu后其优先数就减少1。-C language scheduling process-design courses on operating system design : "Priority number of the highest priority" scheduling algorithm the basic idea is cpu allocated to the parade were in place the highest priority in the process. Dynamic priority, which is priority number in the creation process to set an initial value, When the process is a cpu after its priority on reducing the number of one.
