Some systems can be described as highly scalable, meaning that they will continue to perform well as the volume of data or number of users increases.
I'm looking for a similar word that would describe a system that continues to work well as the complexity of the subject matter it is applied to increases.
Size is to scalable as complexity is to ?
I thought of something like "complexifiable", but that doesn't seem to be a valid English word. I'd like to use this in a context where I'm comparing models or tools, and their varying ability to handle increasing complexity.
