This paper studies constrained Markov decision processes (CMDPs) with constraints against stochastic thresholds, aiming at safety of reinforcement learning in unknown and uncertain environments. We leverage a Growing-Window estimator sampling from interactions with the uncertain and dynamic environment to estimate the thresholds, based on which we design Stochastic Pessimistic-Optimistic Thresholding (SPOT), a novel model-based primal-dual algorithm for multiple constraints against stochastic thresholds. SPOT enables reinforcement learning under both pessimistic and optimistic threshold settings. We prove that our algorithm achieves sublinear regret and constraint violation; i.e., a reward regret of $\tilde{\mathcal{O}}(\sqrt{T})$ while allowing an $\tilde{\mathcal{O}}(\sqrt{T})$ constraint violation over $T$ episodes. The theoretical guarantees show that our algorithm achieves performance comparable to that of an approach relying on fixed and clear thresholds. To the best of our knowledge, SPOT is the first reinforcement learning algorithm that realises theoretical guaranteed performance in an uncertain environment where even thresholds are unknown.

A Minecraft Movie has reportedly surpassed the record previously set by 2023's The Super Mario Bros. Movie for the biggest ever domestic box office opening of a video game adaptation. The new movie, which was released in theaters on Friday, raked in 157 million in the US in its opening weekend, according to The Hollywood Reporter. A Minecraft Movie is doing well internationally, too; THR reports that it's earned 301M altogether in its global debut. The Super Mario Bros. Movie pulled in 146 million in its domestic opening and 377 million globally. A Minecraft Movie stars Jack Black, Sebastian Hansen, Emma Myers, Jason Momoa, Danielle Brooks and Jennifer Coolidge.

Around half of the film's global takings came from North America, according to EntTelligence. The box office numbers come despite reviews for the film being mostly underwhelming. The Telegraph awarded it two stars, saying the charm of the video game was "nowhere to be found", while the Guardian gave it just one star, saying it has "a cobbled-together feel". It does not appear to have stopped families showing up in force to see it. "It has definitely overperformed all industry projections," said Steve Buck, chief strategy officer at EntTelligence, which said the film had enjoyed a late ticket surge.

One person was killed Sunday as Russian air strikes hit the Ukrainian capital, Kyiv, while the death toll from Friday's deadly attack on the central Ukrainian city of Kryvyi Rih continued to rise. The Kyiv victim was found close to the strike's epicenter of the attack in the city's Darnytskyi district, Mayor Vitali Klitschko said. A further three people were injured in the strike, which saw fires break out in several nonresidential areas, damaging cars and buildings. In a statement on social media, Ukrainian President Volodymyr Zelenskyy said the intensifying Russian attacks showed that there is still insufficient international pressure on Moscow.

The Model Context Protocol (MCP) is a standardized interface designed to enable seamless interaction between AI models and external tools and resources, breaking down data silos and facilitating interoperability across diverse systems. This paper provides a comprehensive overview of MCP, focusing on its core components, workflow, and the lifecycle of MCP servers, which consists of three key phases: creation, operation, and update. We analyze the security and privacy risks associated with each phase and propose strategies to mitigate potential threats. The paper also examines the current MCP landscape, including its adoption by industry leaders and various use cases, as well as the tools and platforms supporting its integration. We explore future directions for MCP, highlighting the challenges and opportunities that will influence its adoption and evolution within the broader AI ecosystem. Finally, we offer recommendations for MCP stakeholders to ensure its secure and sustainable development as the AI landscape continues to evolve.
