Cooperation and Competition Coupled Diffusion of Multi-Feature on
Multiplex Networks and its Control
Abstract
Cooperation and competition widely exist in various kinds of network
diffusions which however are usually studied separately. Recently, a
novel network diffusion model, called multi-feature diffusion (MFD),
attracts considerable attentions. The existing works usually assume that
each feature diffuses independently and neglects the possible complex
interplay between different features. In this paper, we introduce the
cooperation and competition into the MFD and propose the
\emph{c}ooperation and
\emph{c}ompetition coupled diffusion of
\emph{m}ulti-\emph{f}eature on
multiplex network (CCMF). An unified framework and mathematical analytic
theory regarding CCMF are then presented which are applicable and
computationally efficient for any number of features and their own
different sub-diffusion dynamics. In addition, an interesting finding is
obtained in CCMF: compared with the high intensity competition,
performing lower intensity competition under weak competition ability is
more easier to result in positive effect. Due to the great importance of
controlling network diffusion in many diverse contexts, we also propose
an optimal allocation strategy of control resource for CCMF which first
realizes the promotion and suppression of network diffusion
simultaneously under one optimization framework and is also verified to
be very efficient.
