+
+LaserTag problem from A. Somani, N. Ye, D. Hsu, &  W. Lee (2013). DESPOT : Online POMDP Planning with Regularization. Advances in Neural Information Processing Systems. This implementaiton has versions with continuous and discrete observations.

 ## Adding New Gallery Examples
 To add new examples, please submit a pull request to the POMDPs.jl repository with changes made to the `gallery.md` file in `docs/src/`. Please include the creation of a gif in the code snippet. The gif should be generated during the creation of the documenation using `@eval` and saved in the `docs/src/examples/` directory. The gif should be named `problem_name.gif` where `problem_name` is the name of the problem. The gif can then be included using `![problem_name](examples/problem_name.gif)`.
