This is the first result to break the O(m+ n log n) time bound of Dijkstra’s algorithm on sparse graphs, showing that Dijkstra’s algorithm is not optimal for SSSP.

Recently, there has been considerable interest in large language models: machine learning systems which produce human-like text and dialogue. Applications of these systems have been plagued by persistent inaccuracies in their output; these are often called “AI hallucinations”. We argue that these falsehoods, and the overall activity of large language models, is better understood as bullshit in the sense explored by Frankfurt (On Bullshit, Princeton, 2005): the models are in an important way indifferent to the truth of their outputs. We distinguish two ways in which the models can be said to be bullshitters, and argue that they clearly meet at least one of these definitions. We further argue that describing AI misrepresentations as bullshit is both a more useful and more accurate way of predicting and discussing the behaviour of these systems.

Long daily commutes can leave little time around busy work days for commuters, who tend to be less physically active, overweight, drink more alcohol, and sleep poorly as a result.

The environmental effectiveness of procurement incentives for electric vehicle (EV) sales depends on the behaviour of EV adopters. This study explores such a relationship and how procurement policies should be designed in order to achieve emissions reduction and be economically efficient.
