    2. 第二句讲island model
    3. 第三、四句讲问题
    4. 第五句引出解决方案HoliDivEvolve

        LLM-Guided Evolutionary Search

        LLM-guided evolutionary search iteratively selects existing programs, uses LLMs as mutation operators to generate a new program, and evaluates it to guide subsequent search. To preserve diversity and reduce the risk of premature convergence, it often adopts the island model, in which groups of programs, called islands, evolve separately.

        The Diversity Challenge

        However, this structure alone does not guarantee distinct search directions, as islands may start from similar programs or converge toward similar solutions during evolution. This suggests that diversity must be considered throughout the search process, from initializing islands with distinct programs to developing island trajectories and sharing discoveries across islands.

        HoliDivEvolve: A Holistic Approach

        To this end, we propose HoliDivEvolve, a holistic approach to establishing and effectively utilizing island diversity throughout evolutionary search. Specifically, we introduce:

        • Diverse initialization to establish different initial programs
        • Trajectory adaptive island selection to allocate computation based on current score, recent growth, and the remaining search budget
        • Growth adaptive migration to share alternative ideas across islands

        Experimental Results

        Experiments across diverse benchmarks show that HoliDivEvolve achieves competitive performance on most evaluated tasks. We further conduct controlled analyses to examine how our design choices affect search behavior and final performance.

        ``` 等等,规则说"保留原文所有信息,不得增删改内容"。我添加的小标题算不算"增"内容?严格来说,小标题是对原文内容的概括,不是原文本身。但规则也说"长文用`

        `/`

        `划分小节",这意味着需要添加小标题。 我认为添加小标题是允许的,因为这是排版的一部分,不是改变原文内容。但我需要确保小标题不改变原文意思。 让我再检查一下是否有遗漏或改变的内容。 原文: "LLM-guided evolutionary search iteratively selects existing programs, uses LLMs as mutation operators to generate a new program, and evaluates it to guide subsequent search.

        `包含了这些文字 ✓ 原文"However..."到"across islands." → 我的`

        `包含了这些文字 ✓ 原文"To this end..." → 我的`

        `包含了这些文字,但"Specifically, we introduce:"后面用了列表,原文是"Specifically, we introduce diverse initialization to establish different initial programs, trajectory adaptive island selection to allocate computation based on current score, recent growth, and the remaining search budget, and growth adaptive migration to share alternative ideas across islands." 这里有个问题:我把"Specifically, we introduce:"作为引导句,然后把后面的内容拆成了三个列表项。这样改变了原文的结构。原文是一句话,我把它拆成了列表。 但规则说"列表内容用`

        • `",而且原文确实有三个并列的组件,用列表展示是合理的。 不过为了严格"不得增删改内容",我需要确保列表项的文字完全来自原文。 让我重新考虑:原文说"Specifically, we introduce diverse initialization to establish different initial programs, trajectory adaptive island selection to allocate computation based on current score, recent growth, and the remaining search budget, and growth adaptive migration to share alternative ideas across islands." 如果我要把它拆成列表,我需要: - 引导句:"Specifically, we introduce:" —— 这是原文的一部分 - 列表项1:"diverse initialization to establish different initial programs" —— 原文的一部分 - 列表项2:"trajectory adaptive island selection to allocate computation based on current score, recent growth, and the remaining search budget" —— 原文的一部分 - 列表项3:"growth adaptive migration to share alternative ideas across islands" —— 原文的一部分 这样拆分是合理的,所有文字都保留了。 让我最终确定HTML输出: ```html
