Reproducibility Variable Result LLM Response
Research Type Experimental We demonstrate our approach using data from a real-world deployment of unmanned underwater vehicles in extreme environments. We demonstrate and evaluate our framework by simulated experiments based on the UUV example of Fig. 1.

Pseudocode No No pseudocode or algorithm blocks were found in the paper.
Open Source Code No The paper does not provide any statements about open-source code availability or links to code repositories.
Open Datasets No We illustrate our new method with an example of an unmanned underwater vehicle (UUV) in the context of a valve turning scenario from the PANDORA2 project which created UUVs that keep going under extreme uncertainty. and to simulate and collect data of both previous missions and the current one for the pre-mission and runtime verifications respectively, we use the PRISM simulation module. No concrete access information for the used data is provided.
Dataset Splits No The paper does not provide specific details about training, validation, or test dataset splits.
Hardware Specification No The paper does not provide specific hardware details (e.g., GPU/CPU models, memory amounts) used for running its experiments.
Software Dependencies No We use the tool PRISM (Kwiatkowska, Norman, and Parker 2011) and using the Para MC engine of PRISM. No specific version numbers for PRISM or other software dependencies are provided.
Experiment Setup Yes First, to simulate and collect data of both previous missions and the current one for the pre-mission and runtime verifications respectively, we use the PRISM simulation module by assuming the true unknown transitions probabilities in Fig. 1 are: a1 = 0.05, a2 = 0.03, b1 = 0.2, b2 = 0.1, x = 10 5, y = 0.001, v = 0.3, w = 0.01. For the optimal policy of state 1, we assign a random number in [25/40] for γ in each simulated mission to mimic the practical case of changing policies. Then, it results in 49 previous missions and a 50-th as the current one which explicitly using γ = 0.75 as the optimal probabilistic policy of state 1. At the pre-mission stage, given the data of previous 49 missions...together with the prior knowledge in Table 1, the posteriors by our Bayesian estimators are also listed there.
