Ulcerative colitis (UC) is an inflammatory disease of the rectal and colonic mucosa and seems to result from a complex series of interactions between susceptibility genes, the environment and the immune system. Various components of the mucosal immune system are implicated in the immunopathogenesis of UC. Evidence from animal models also suggests that an(More)
The capacitated vehicle routing problem with time-dependent travel times has many real-life applications. Due to the computational complexity, metaheuristics are commonly used to solve the problem. In this paper, a relatively new metaheuristic, Artificial Bee Colony (ABC) algorithm, is developed to solve the problem. Besides, the ABC algorithm is revised to(More)
