Summary:
Ensuring that parents in recomposed families see their children regularly is a complex network problem, according to a new study. The lead researcher set out to resolve one of his real-life problems: finding a suitable weekend for both partners in his recomposed family to see all their children at the same time. He then joined forces with a mathematician and a complex systems expert. The answer they came up with is that such an agreement is not possible, in general.

Physics can provide insights into societal trends. Problems involving interactions between people linked in real-life networks can be better understood by using physical models. As a diversion from his normal duties as a theoretical physicist, Andrés Gomberoff from the Andres Bello University in Santiago, Chile, set out to resolve one of his real-life problems:  finding a suitable weekend for both partners in his recomposed family to see all their children at the same time. He then joined forces with a mathematician and a complex systems expert. This resulted in a study published in EPJ B, showing that solving this problem essentially equates to minimizing the energy in a material model.

The authors assume that they deal with a network of people who are connected, either because they are in a current relationship or because they are ex-partners. Another assumption is that all involved in the network are willing to cooperate and communicate in an open manner.

They then attempt to verify whether it is possible to find a custody arrangement whereby all parents see all of their children together every other weekend, thus satisfying the expectations of all members of the network. The answer is that it is not possible, in general, to have such an agreement. 

However, they also found that it is possible to have an arrangement in which one of the parents gets to see all of their children every other weekend.  They also found an algorithm to maximize the level of contentment of members of this extended family network. Maximizing the number of parents spending time with their own children and those of their current partners was akin to minimizing the energy of a particular magnetic material called a spin glass.

Who said that physics can’t have real-life applications?
