You can just use R packages to build a new hybrid meta-heuristic for some problem domains such as traveling salesman problem using GA, DE with machine learning packages
You can apply quantum inspired swarm intelligence. Since quantum based applications are multi-faced in nature, the algorithm can cover multi-modal aspect of intrusion. Quantum PSO can be one suitable approach. You can also substantiate the proposal with some mathematical convergence proofs. You can refer to an article on Evolutionary PSO.
