Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：The complexity of computing Markov perfect equilibrium in general-sum stochastic games
一般 随机博弈 马尔可夫完美均衡 计算复杂性
2023/5/12
Similar to the role of Markov decision processes in reinforcement learning, Markov games (also known as stochastic games) form the basis for the study of multi-agent reinforcement learning and sequenc...

Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Does qubit connectivity impact quantum circuit complexity
量子比特连接 量子电路 复杂性
2023/4/13
Some physical implementation schemes of quantum computing -- such as those based on superconducting qubits, quantum dots, and cold atoms -- can apply two-qubit gates only on certain pairs of qubits. O...
With plants as a model, studying the ‘complexity and reproducibility’ of developmental biology（图）
植物 发育生物学 分子机制
2023/7/11
Nearly paper-thin, often with a complex two-dimensional shape, leaves may number into the hundreds of thousands on an organism like a white oak. Yet typically, each leaf appears quite similar in form.

evolutionary clues honeybees social complexity
2020/2/20
The complex social life of honeybees -- with their queens and workers cooperating to produce honey -- is deeply entrenched in the public's imagination. But the majority of the world's more than 20,000...
Structural complexity in forests improves carbon capture（图）
Structural complexity forests carbon capture
2019/10/17
Forests in the eastern United States that are structurally complex -- the arrangement of vegetation is varied throughout the physical space -- sequester more carbon, according to a new study in Ecolog...
Food and Fear:Modeling animal tradeoffs shaped by landscape complexity
Food Fear animal tradeoffs shaped landscape complexity
2016/11/4
The Lemhi Valley is a high desert sagebrush steppe environment in eastern Idaho, along the border with Montana. It's a critical habitat and a gorgeous piece of intact sagebrush landscape, according to...
On the computability-theoretic complexity of trivial, strongly minimal models
computability-theoretic strongly minimal models
2015/9/28
We show the existence of a trivial, strongly minimal (and thus
uncountably categorical) theory for which the prime model is computable and
each of the other countable models computes 0
00. This res...

Karp complexity and classes with the independence property
Karp complexity independence property
2015/9/25
A class K of structures is controlled if for all cardinals
λ, the relation of L∞,λ-equivalence partitions K into a set of
equivalence classes (as opposed to a proper class). We prove that
no pseudo...
Source complexity of the May 20,2012,Mw 5.9,Ferrara (Italy) event
Empirical Green's functions Array analysis
2015/8/26
A Mw 3.9 foreshock on May 19, 2012, at 23:13 UTC, was followed at 02:03 on May 20, 2012, by a Mw 5.9 earthquake that hit a densely populated area in the Po Plain, west of the city of Ferrara, Italy (F...
Filter design with low complexity coefficients
Heuristic design low complexity coefficient filters with nonzero number the filter coefficients
2015/8/10
We introduce a heuristic for designing filters that have low complexity coefficients, as measured by the total number of nonzeros digits in the binary or canonic signed digit (CSD) representations of ...
Communication Complexity and Coordination by Authority
Authority Complexity and Coordination
2015/7/31
We prove that the simplest communication allowing two players to coordinate on a course
of action is authority (letting one player choose an action). We also consider the case where
each player poss...
Simple Bounds for Recovering Low-complexity Models
`1-norm minimization nuclear-norm minimization block-sparsity duality random matrices
2015/6/17
This note presents a unified analysis of the recovery of simple objects from random linear measurements. When the linear functionals are Gaussian, we show that an s-sparse vector in Rn can be efficien...
On the complexity of surface ruptures during normal faulting earthquakes: excerpts from the 6 April 2009 L'Aquila (central Italy) earthquake (Mw 6.3)
On the complexity surface ruptures normal faulting earthquakes L'Aquila earthquake
2015/1/6
Over the past few years the assessment of the earthquake potential of large continental faults has increasingly relied on field investigations. State-of-the-art seismic hazard models are progressively...
