Bifurcations in adaptive vascular networks: towards model calibration
Konstantin Klemm, Erik Andreas Martens
Transport networks are crucial for the functioning of natural and technological systems. We study a mathematical model of vascular network adaptation, where the network structure d…
Optimisation via encodings: a renormalisation group perspective
Konstantin Klemm, Anita Mehta, Peter F. Stadler
Difficult, in particular NP-complete, optimization problems are traditionally solved approximately using search heuristics. These are usually slowed down by the rugged landscapes e…
Order-disorder transition in the zero-temperature Ising model on random graphs
Armin Pournaki, Eckehard Olbrich, Sven Banisch +1
The zero-temperature Ising model is known to reach a fully ordered ground state in sufficiently dense random graphs. In sparse random graphs, the dynamics gets absorbed in disorder…
Exact statistical mechanics of the Ising model on networks
Konstantin Klemm
The Ising model is an equilibrium stochastic process used as a model in several branches of science including magnetic materials, geophysics, neuroscience, sociology and finance. R…
Tree decompositions of real-world networks from simulated annealing
Konstantin Klemm
Decompositions of networks are useful not only for structural exploration. They also have implications and use in analysis and computational solution of processes (such as the Isin…
Altruism in populations at the extinction transition
Konstantin Klemm, Nagi Khalil
We study the evolution of cooperation as a birth-death process in spatially extended populations. The benefit from the altruistic behavior of a cooperator is implemented by decreas…
