Methods and systems for optimizing topology of a wireless backhaul communication network are disclosed. The network comprises a plurality of nodes. Each node reports load type information, indicative of data generation requirements of connected devices, and link quality information, indicative of communication link quality with neighboring nodes, to a controller. Due to the large number of possible network topologies, which precludes exhaustive evaluation, a non-analytical shortcut process is used to generate a subset of candidate network topologies. This process identifies candidate topologies based on the received load type and link quality information. The network is configured according to a selected topology from the subset, and its actual performance is measured. If performance is unsatisfactory, the network is reconfigured using another topology from the subset. The non-analytical shortcut process may utilize an AI model, a heuristic algorithm, or a combination thereof. A method of training such AI model is also presented.
