An adaptive learning pigeon-inspired optimization based on mutation disturbance (ALPIO) is proposed for solving the problems of fuel consumption and threat avoidance in spacecraft cluster orbit reconstruction. First. considering the constraints of maintaining a safe distance between adjacent spacecraft within the spacecraft cluster and of avoiding space debris. the optimal performance... https://qxsjwjsdu2yw.blog2freedom.com/34914109/conflict-resolution-between-multi-level-government-and-farmers-in-land-expropriation-based-on-institutional-credibility-theory-empirical-evidence-from-shandong-province-china
