Maximizing a psychological uplift in love dynamics

Abstract

In this chapter, we investigate the dynamical properties of a psychological uplift in lovers. We first evaluate extensively the dynamical equations which were recently given by Rinaldi et al. (Physica A, 392: 3231–3239, 2013). Then, the dependences of the equations on several parameters are numerically examined. From the viewpoint of lasting partnership for lovers, especially, for married couples, one should optimize the parameters appearing in the dynamical equations to maintain the love for their respective partners. To achieve this optimization, we propose a new idea where the parameters are stochastic variables and the parameters in the next time step are given as expectations over a Boltzmann–Gibbs distribution at a finite temperature. This idea is very general and might be applicable to other models dealing with human relationships.
