    Computational Efficiency(计算效率) 指算法或系统在执行任务时,以最小的时间和计算资源消耗达到预期目标的能力。其核心在于优化计算过程中的时间复杂度和空间复杂度,确保在有限资源下完成高性能运算。

    从技术层面看,计算效率包含两个维度:

    1. 时间效率:衡量算法执行速度,通常用时间复杂度表示。例如,快速排序算法的时间复杂度为$O(n log n)$,比冒泡排序的$O(n)$更高效(来源:MIT OpenCourseWare《算法导论》)。
    2. 空间效率:评估内存占用情况。例如,动态规划通过存储中间结果减少重复计算,可能以空间换时间(来源:Stanford University《算法设计与分析》)。

    在工程应用中,计算效率直接影响系统性能。例如,深度学习模型通过优化矩阵运算(如使用GPU加速)提升训练速度(来源:arXiv论文《Deep Learning Optimization Methods》)。此外,嵌入式系统常需平衡效率与功耗,如实时操作系统通过精简调度算法降低延迟(来源:IEEE Xplore《嵌入式系统设计》)。

    网络扩展资料

    “Computational efficiency”(计算效率)是计算机科学和工程领域的核心概念,指在有限的计算资源(如时间、内存、能耗等)下,系统或算法完成任务的最优程度。其核心目标是用更少的资源实现更高的性能,具体可从以下维度解析:


    一、核心定义


    二、关键指标

    1. 时间复杂度:衡量运算步骤随输入规模增长的变化趋势。
    2. 空间复杂度:评估内存占用与输入规模的关系。
    3. 能耗效率:在移动设备或嵌入式系统中,降低计算能耗尤为重要。

    三、优化方法


    四、应用场景


    五、实际案例


    计算效率的提升需在时间、空间和能耗之间权衡取舍,具体优化策略需结合应用场景和资源限制。
