They have learnt that these policies increase sex tourism, people-trafficking and criminality.
Once the simulated results are accurate enough, in a second step, the learnt-in-simulation policy is transferred to the vehicle where the learning procedure continues in a real environment, improving the initial policy.
It is developed with an heuristic belief that if both the value function can be approximated with sufficient accuracy and optimal policies with respect to the approximated value function can be learnt, then the true optimal policy can be approximated with sufficient accuracy.
This section also highlights the lesson learnt from the model simulation, policy implication, and trade-offs needed to pull the West African electricity system away from its current state.
As I said earlier (see 8.45m), quoting Osborne's biographer, at some stage early in his career Osborne learnt "the primacy of politics over policy" and today that philosophy was fully on display.
Asked at his conference in Newcastle this month the greatest lesson he had learnt since taking office, he replied ruefully: "I have learnt, and frankly I've learnt it the hard way over the last year and a half, you can't spring on to the public a solution or a policy if you don't spend a lot of time first explaining what the problem is.
The WHO recommended that international experience be reviewed, lessons learnt and best practices in implementing policies, plans and programs be shared [ 49].
The resulting performance observed (see Figure 10) indicates that the benefit of using the policies, derived (i.e. learnt) over successive iterations, is around a factor of 2 compared with having no policies (i.e. statically configured channels).
This suggests that the lessons from the housing bubble that contributed to the financial crisis have not been learnt and that orthodox thinking on housing policy remains entrenched in Whitehall".
It is also important to consider cultural, financial, and educational barriers to changing policy and lessons should be learnt from practices of previous programs like iron+folic acid supplementation schemes in these countries.
