连续布局

异构矩形组件、连续布局生成器，使用脚本layout_generator_c 配合配置文件与命令行参数生成所布局图像与温度场数据。

采样方法

  • [x] 按顺序摆放 (对应参数 sampler: sequence)
    • 参数要求：每个组件的尺寸需满足 unit_x / length * nx 与 unit_y / length * nx 为偶数
  • [x] Gibbs 采样 (对应参数 sampler: gibbs)

用法

  1. 使用配置文件或命令行生成数据集，比如以默认配置文件 default_c.yml 生成数据集，其中 default_c.yml 在目录 utils 下。
  2. 或使用自定义配置文件 --config 配置文件路径
    • 配置文件以 YAML 格式存储

Generate layout dataset. Args that start with '--' (eg. --test) can also be
set in a config file (/home/fenics/shared/layout-
generator/layout_generator/utils/default_c.yml or specified via --config). The
config file uses YAML syntax and must represent a YAML 'mapping' (for details,
see http://learn.getgrav.org/advanced/yaml). If an arg is specified in more
than one place, then commandline values override config file values which
override defaults.

示例

用法与离散布局相同，但需要指定每个组件参数，同时注意 sampler 参数指定采样方法。

参数说明

  • units: 每个组件的宽与高
  • powers: 每个组件的功率
  • angles: 每个组件的摆放角度，暂时支持 0 与 90
  • sampler: 采样方法
