Summary: Multiobjective multitask optimization (MMO) aims to solve multiple problems simultaneously. This study proposes an MMO algorithm that uses transfer rank and a KNN model to achieve this goal. The algorithm introduces the concept of transfer rank to quantify the priority of transfer solutions and improve the likelihood of positive results. Solutions are sorted based on transfer rank, with higher-ranked solutions assumed to be more suitable for transfer. The algorithm also prioritizes previous and positive-transfer solutions and uses a KNN model classifier to distinguish solutions with the same transfer rank. Experimental results demonstrate that the proposed algorithm is more effective than other conventional MMO techniques.

Summary: Evolutionary multitasking (EMT) is a new research topic that aims to improve convergence across multiple optimization tasks by facilitating knowledge transfer. Existing EMT algorithms are limited to homogeneous problems, and little effort has been made to generalize EMT for solving heterogeneous problems. This article proposes a novel rank loss function to achieve superior intertask mapping and derive an analytical solution for affine transformation. The proposed technique can seamlessly integrate with EMT paradigms, and its effectiveness is demonstrated through experiments on synthetic multitasking and many-tasking benchmark problems.
