摘要:

Описание: Fast is good, and this book gets you up to speed with Android X programming quickly and efficiently without wasting readers time explaining concepts that they are already familiar with. Android SDK Programming For Dummies provides the perfect solution for readers who already know how to program and just want to know about programming in the Android environment and the ins and outs of the latest Android SDK. Readers who are already familiar with object-oriented programming and syntax will find that Android SDK X Programming For Dummies provides more of what theyre looking for and less of what they already understand. The book begins by demonstrating a fully functional application that demonstrates a wide variety of Android features, including user interface design, application management, data and content management, incorporating external services, and interacting with hardware, the operating system, and networking. The book then goes through the process of building the application, creating the emulator, and running the application. The sample application demonstrates Android programming best practices, as developed by a professor with years of experience helping students with programs and anticipating pitfalls. The book then organizes the many packages of the Android SDK by functionality and tells the reader about which standards and features are appropriate for each level of Android SDK (because sometimes programmers want their applications to be written for an older Android version that may be in more widespread usage). New features of the latest Android SDK are explained fully with many programming examples and snippets that demonstrate how to effectively incorporate the features into new or existing applications. All programming examples, including the sample application, are available for download from the books website. Series features -- Like all For Dummies books, this book will be written in clear, plain English explanations and careful organization that make For Dummies the easiest way for experienced programmers to get up to speed quickly!

内容概要:本文介绍了一个基于冠豪猪优化算法(CPO)的无人机三维路径规划项目,利用Python实现了在复杂三维环境中为无人机规划安全、高效、低能耗飞行路径的完整解决方案。项目涵盖空间环境建模、无人机动力学约束、路径编码、多目标代价函数设计以及CPO算法的核心实现。通过体素网格建模、动态障碍物处理、路径平滑技术和多约束融合机制,系统能够在高维、密集障碍环境下快速搜索出满足飞行可行性、安全性与能效最优的路径,并支持在线重规划以适应动态环境变化。文中还提供了关键模块的代码示例,包括环境建模、路径评估和CPO优化流程。; 适合人群:具备一定Python编程基础和优化算法基础知识,从事无人机、智能机器人、路径规划或智能优化算法研究的相关科研人员与工程技术人员,尤其适合研究生及有一定工作经验的研发工程师。; 使用场景及目标:①应用于复杂三维环境下的无人机自主导航与避障;②研究智能优化算法(如CPO)在路径规划中的实际部署与性能优化;③实现多目标(路径最短、能耗最低、安全性最高)耦合条件下的工程化路径求解;④构建可扩展的智能无人系统决策框架。; 阅读建议:建议结合文中模型架构与代码示例进行实践运行,重点关注目标函数设计、CPO算法改进策略与约束处理机制,宜在仿真环境中测试不同场景以深入理解算法行为与系统鲁棒性。
