Complexity Digest wrote a new blog post titled Addressing the minimum fleet problem in on-demand urban mobility
Information and communication technologies have opened the way to new solutions for urban mobility that provide better ways to match individuals with on-demand vehicles. However, a fundamental unsolved problem is how best to size and operate a fleet of vehicles, given a certain demand for personal mobility. Previous studies1,2,3,4,5 either do not provide a scalable solution or require changes in human attitudes towards mobility. Here we provide a network-based solution to the following ‘minimum fleet problem’, given a collection of trips (specified by origin, destination and start...

Complexity Digest wrote a new blog post titled Predicting the temporal activity patterns of new venues
Estimating revenue and business demand of a newly opened venue is paramount as these early stages often involve critical decisions such as first rounds of staffing and resource allocation. Traditionally, this estimation has been performed through coarse-grained measures such as observing numbers in local venues or venues at similar places (e.g., coffee shops around another station in the same city). The advent of crowdsourced data from devices and services carried by individuals on a daily basis has opened up the possibility of performing better predictions of temporal visitation...
Complexity Digest wrote a new blog post titled Cooperative Object Transport in Multi-Robot Systems: A Review of the State-of-the-Art
In recent years, there has been a growing interest in designing multi-robot systems (hereafter MRSs) to provide cost effective, fault-tolerant and reliable solutions to a variety of automated applications. Here, we review recent advancements in MRSs specifically designed for cooperative object transport, which requires the members of MRSs to coordinate their actions to transport objects from a starting position to a final destination. To achieve cooperative object transport, a wide range of transport, coordination and control strategies have been proposed. Our goal is to provide a...

Eurekahedge has recently concluded its fifth annual survey of asset managers with mandates to invest in Japan. In the words of Eurekahedge chairman and CEO, Satoshi Iwanaga: “Survey results for 2018 suggest that central bank normalization is still a long way off in Japan, with investors continuing to reduce theirRead More

Complexity Digest wrote a new blog post titled The Human Takeover: A Call for a Venture into an Existential Opportunity
We propose a venture into an existential opportunity for establishing a world ‘good enough’ for humans to live in. Defining an existential opportunity as the converse of an existential risk—that is, a development that promises to dramatically improve the future of humanity—we argue that one such opportunity is available and should be explored now. The opportunity resides in the moment of transition of the Internet—from mediating information to mediating distributed direct governance in the sense of self-organization. The Internet of tomorrow will mediate the execution of contracts,...

Complexity Digest wrote a new blog post titled When Robots Get Bored and Invent Team Sports: A More Suitable Test than the Turing Test?
Increasingly, the Turing test—which is used to show that artificial intelligence has achieved human-level intelligence—is being regarded as an insufficient indicator of human-level intelligence. This essay extends arguments that embodied intelligence is required for human-level intelligence, and proposes a more suitable test for determining human-level intelligence: the invention of team sports by humanoid robots. The test is preferred because team sport activity is easily identified, uniquely human, and is suggested to emerge in basic, controllable conditions. To expect humanoid...

Complexity Digest wrote a new blog post titled Will the New Ring Vaccination Stop the Spread of Ebola?
The World Health Organization (WHO) and news reports are describing the deployment of a new experimental vaccine for Ebola in the Democratic Republic of the Congo (DRC). Originally 4,000 doses were sent to the country, and while the number is growing to 8,000 or more, there are still not enough to widely inoculate the city of Mbandaka with a population of over a million. Reports describe how the vaccine will be used in a "ring vaccination" technique. In ring vaccination, those who are most likely to be infected receive the vaccine. Currently this is being done by inoculating...

[A version of this post appears on the O'Reilly Radar.]The O'Reilly Data Show Podcast: A special episode to mark the 100th episode.This episode of the Data Showmarks our 100th episode. This podcast stemmed out of video interviews conducted at O’Reilly’s 2014 Foo Camp. We had a collection of friends who were key members of the data science and big data communities on hand and we decided to record short conversations with them. We originally conceived of using those initial conversations to be the basis of a regular series of video interviews. The logistics of studio interviews proved too...

Complexity Digest wrote a new blog post titled Symbolic Unity, Dynastic Continuity, and Countervailing Power: Monarchies, Republics, and the Economy
We investigate the implications of the persistence of traditional patterns of state organization by examining the relationship between property rights and the economy for monarchies and republics. We argue that, relative to republics, monarchies protect property rights to a greater extent by reducing the negative effects of internal conflict, executive tenure, and executive discretion. In turn, a better protection of property rights results in greater standards of living. Using panel data on 137 countries between 1900 and 2010, we formulate and test a model with endogenous variables....
