Determining the least expensive path for a new subway line underneath a metropolis like New York City is a colossal planning challenge—involving thousands of potential routes through hundreds of city ...

The original version of this story appeared in Quanta Magazine. If you want to solve a tricky problem, it often helps to get organized. You might, for example, break the problem into pieces and tackle ...

Abstract: Finding high-quality solutions quickly is an important objective in motion planning. This is especially true for highdegree- of-freedom robots. Satisficing planners have traditionally found ...

For non-planar graphs, such solutions are computationally intractable," explained the researchers. The algorithm relies on the Kac-Ward formalism, a mathematical method that allows exact computation ...

Abstract: The paper introduces an asymptotically optimal lifelong sampling-based path planning algorithm that combines the merits of lifelong planning algorithms and lazy search algorithms for rapid ...

The original version of this story appeared in Quanta Magazine. If you’ve been making the same commute for a long time, you’ve probably settled on what seems like the best route. But “best” is a ...

The November 2024 core update took three weeks to complete. With the update complete, now is the time to analyze traffic changes. Recovery from ranking drops can take several months with no guaranteed ...

The official opening of the Foster + Partners-designed Alibaba Shanghai Campus office building, rooted in the city's DNA of innovation and openness, redefines the traditional office environment. The ...

This work considers the sample and computational complexity of obtaining an ε-optimal policy in a discounted Markov Decision Process (MDP), given only access to a generative model. In this model, the ...
