Abstract
We present a prototypical multimodal optimisation problem from the systems biology domain—tuning the kinetic parameters of a reduced order gene regulatory network (GRN) model to obtain optimal fits to gene expression timeseries. After introducing the problem, the chapter then illustrates different fitness landscapes of the GRN parameter fitting problem using various statistical plots of landscape features, along with local optima networks (LONs)—graphs representing local optima (modes), their basin sizes and connectivity across the landscape. In a typical multimodal optimisation process, the problem owners get presented with a putative list of modal solutions from which to verify and select a design. We argue in this chapter that it is often useful to present a characterisation of the search landscape itself along with the list of modal solutions. The characterisation of the search landscape can provide insight into the domain, and may guide, for instance, problem reformulations, or the final mode selection based on broader features than simply mode performance, e.g. basin size if robustness of modes is a concern.
