MergeDJD: A Fast Constructive Algorithm with Piece Merging for the Two-Dimensional Irregular Bin Packing Problem
Yi Zhou, Haocheng Fu, Yiping Liu +3
The two-dimensional irregular bin packing problem (2DIBPP) aims to pack a given set of irregular polygons, referred to as pieces, into fixed-size rectangular bins without overlap,…
Numerical Linear Algebra in Linear Space
Yiping Liu, Hoai-An Nguyen, Junzhao Yang
We present a randomized linear-space solver for general linear systems with and $\mathbf{b} \in \mathb…
Kimi K2: Open Agentic Intelligence
Kimi Team, Yifan Bai, Yiping Bao +195
We introduce Kimi K2, a Mixture-of-Experts (MoE) large language model with 32 billion activated parameters and 1 trillion total parameters. We propose the MuonClip optimizer, which…
OJBench: A Competition Level Code Benchmark For Large Language Models
Zhexu Wang, Yiping Liu, Yejie Wang +9
Recent advancements in large language models (LLMs) have demonstrated significant progress in math and code reasoning capabilities. However, existing code benchmark are limited in…
A Reduction-Driven Local Search for the Generalized Independent Set Problem
Yiping Liu, Yi Zhou, Zhenxiang Xu +2
The Generalized Independent Set (GIS) problem extends the classical maximum independent set problem by incorporating profits for vertices and penalties for edges. This generalized…
Data Pricing for Graph Neural Networks without Pre-purchased Inspection
Yiping Liu, Mengxiao Zhang, Jiamou Liu +1
Machine learning (ML) models have become essential tools in various scenarios. Their effectiveness, however, hinges on a substantial volume of data for satisfactory performance. Mo…
Efficient Top-k s-Biplexes Search over Large Bipartite Graphs
Zhenxiang Xu, Yiping Liu, Yi Zhou +2
In a bipartite graph, a subgraph is an -biplex if each vertex of the subgraph is adjacent to all but at most vertices on the opposite set. The enumeration of -biplexes fr…
Efficient size-prescribed -core search
Yiping Liu, Bo Yan, Bo Zhao +3
-core is a subgraph where every node has at least neighbors within the subgraph. The -core subgraphs has been employed in large platforms like Network Repository to compr…
Behaviour Modelling of Social Animals via Causal Structure Discovery and Graph Neural Networks
Gaël Gendron, Yang Chen, Mitchell Rogers +11
Better understanding the natural world is a crucial task with a wide range of applications. In environments with close proximity between humans and animals, such as zoos, it is ess…
Centralization Problem for Opinion Convergence in Decentralized Networks
Yiping Liu, Jiamou Liu, Bakhadyr Khoussaino +2
This paper aims to provide a new perspective on the interplay between decentralization -- a prevalent character of multi-agent systems -- and centralization, i.e., the task of impo…
From the Periphery to the Center: Information Brokerage in an Evolving Network
Bo Yan, Yiping Liu, Jiamou Liu +3
Interpersonal ties are pivotal to individual efficacy, status and performance in an agent society. This paper explores three important and interrelated themes in social network the…
