2017年5月30日 · We propose Constrained Policy Optimization (CPO), the first general-purpose policy search algorithm for constrained reinforcement learning with guarantees for near-constraint satisfaction at each iteration.

We propose Constrained Policy Optimization (CPO), the first general-purpose policy search algorithm for constrained reinforcement learning with guarantees for near-constraint satisfaction at each iteration.

Constrained Policy Optimization(CPO)[1]是解决CMDP的一个经典算法。通过local policy search + trust region recovery的方法将单步策略更新限定在不违反约束的增长方向上。原理和NPG[2]或TRPO[3]基本相同，区别在于引入了环境约束： 实际操作时候也是进行了一阶和二阶近似：

2017年7月6日 · CPO is a trust region method for constrained RL which approximately enforces the constraints in every policy update. It uses approximations of the constraints to predict how much the constraint costs might change after any given update, and then chooses the update that will most improve performance while keeping the constraint costs below their ...

2017年2月3日 · The document summarizes key findings from the Deloitte Global CPO Survey 2017, which received responses from 480 procurement leaders from 36 countries representing $4.9 trillion in annual turnover. The survey found that cost reduction remains the top priority for CPOs as they look to support growth in an uncertain market.
