A new constructive heuristic driven by machine learning for the traveling salesman problem

Mele, Umberto Junior ; Gambardella, Luca Maria ; Montemanni, Roberto

In: Algorithms, 2021, vol. 14, no. 9, p. 25

Recent systems applying Machine Learning (ML) to solve the Traveling Salesman Problem (TSP) exhibit issues when they try to scale up to real case scenarios with several hundred vertices. The use of Candidate Lists (CLs) has been brought up to cope with the issues. A CL is defined as a subset of all the edges linked to a given vertex such that it contains mainly edges that are believed to be...

The Impact of Cultural Intelligence on Communication Effectiveness, Job Satisfaction and Anxiety for Chinese Host Country Managers Working for Foreign Multinationals

Bücker, Joost J.L.E. ; Furrer, Olivier ; Poutsma, Erik ; Buyens, Dirk

In: The International Journal of Human Resource Management, 2014, vol. 25, no. 14, p. 2068-2087

Cultural intelligence (CQ) is an important construct attracting growing attention in academic literature and describing cross-cultural competencies. To date, researchers have only partially tested the relationship between CQ and its dependent variables, such as performance. In this study, the relationship between CQ and communication effectiveness and job satisfaction is measured in a sample...

A Hierarchical Framework of New Products Development : an Example from Biotechnology

Alexandre, Maria Tereza ; Furrer, Olivier ; Sudharshan, D.

In: European Journal of Innovation Management, 2003, vol. 6, no. 1, p. 48-63

Many new products are based on new technologies, which may in turn be based on new scientific discoveries. The extant literature on new product development has focused on how a firm may successfully commercialize new products. There is a corporate cost associated with new product failure, which extends beyond the final product-manufacturing corporation to all the parties involved in the...

A Neighborhood for Complex Job Shop Scheduling Problems with Regular Objectives

Bürgy, Reinhard

In: Journal of Scheduling, 2017, vol. 20, p. 391-422

Due to the limited applicability in practice of the classical job shop scheduling problem, many researchers have addressed more complex versions of this problem by including additional process features, such as time lags, setup times, and buffer limitations, and have pursued objectives that are more practically relevant than the makespan, such as total flow time and total weighted tardiness....

A decision-supporting framework for job automation and soft skills development, with job criticality as a linchpin

Riva, Goga

Mémoire de bachelor : Haute école de gestion de Genève, 2020 ; TDIBM 101.

The Fourth Industrial Revolution represents both challenges and opportunities for companies, but more importantly, it raises questions about what decisions should be made and what their implications would be. There are two dimensions to this new era of economic disruption that can be seen as opposed or complementary: job automation and soft skill development for humans. Often, discussing...

Parallel heuristic community detection method based on node similarity

Zhou, Qiang ; Cai, Shi-Min ; Zhang, Yi-Cheng

In: IEEE Access, 2019, vol. 7, p. 184145–184159

Community structure discovery can help us better understand the capabilities and functions of the network. However, many existing methods have failed to identify nodes in communities accurately. In this paper, we proposed a heuristic community detection method based on node similarities that are computed by assigning different edge weight influence factors based on different neighbor types of...
