很久没有写有关技术的博客了,今天打算和大家分享一下我们在今年SIGGRAPH Asia上的一篇工作:Learning-based 2D Irregular Shape Packing. 我这里住要和大家分享这个项目的思考历程,具体的技术细节大家可以参考paper。 顾名思义,我们打算解决的问题,就是对任意输入的2D不规则形状,搜索得到一个紧凑的拼接方案。
To our knowledge, this is the first approach to use a dense reward to address the 2D irregular packing problem. Building on our earlier work, we improve the deep neural network by incorporating the Double Deep Q-Network (DDQN) framework to enhance our deep Q-learning approach, reducing ...

2D-Bin-Packing This project aims to provide basic functionality for solving 2D bin packing problems of irregular (and regular) sets of pieces. The 2D Bin packing problem consists of, given a set of 2D pieces with unknown form or shape, we have to place them in a series of rectangular bin...
We present an optimized numerical algorithm based on the multigrid approach for solving the pressure equation in 2D problems of fluid-fluid displacement. This type of problems arise in oilfield services applications, such as drilling, cementing, hydraulic fracturing and EOR. The displacement of fluids...
