pomdp 0.99.0 (05/04/2020)

Changes

• Support finite-horizon POMDPs and store epochs.
• reward now looks at different epochs, calculates the optimal actions and the parameter names are improved.
• solve_POMDP not looks at convergence.
• solve_POMDP gained parameter terminal_values.
• solve_POMDP gained parameter discount to overwrite the discount rate specified in the model.
• solve_POMDP can now solve POMDPs with time-dependent transition probabilities, observation probabilities and reward structure.
• solve_POMDP gained parameter grid in parameter list to specify a custom belief point grid for the grid method.
• write_POMDP and solve_POMDP gained parameter digits.
• added read_POMDP to read POMDP files.
• plot for POMDP is now replaced by plot_policy_graph.
• added policy graph visualization with vizNetwork.
• added plot_value_function.
• added function sample_belief_space to sample from the belief space.
• added function plot_belief_space.
• added function transition_matrix.
• added function observation_matrix.
• added function reward_matrix.
• POMDP model now also contains horizon and terminal_values.
• added MDP formulated as a POMDP.
• added policy function to extract a better readable policy.
• added update_belief.
• added simulate_POMDP.
• added round_stochastic.
• added optimal_action.
