Tourist trip planning: solo versus group traveling

Tourism activities are mostly done in groups, where tourists <br> enjoy their trip in company of their relatives or friends. <br> Hence, in this paper, we present an approach on how to <br> solve the problem trip planning for a group of tourists. An <br> algorithm that was developed for a single tourist trip is <br> applied in the context of group trip. The solo, subgroup and <br> group tourist trip are discussed and compared. New test <br> instances based on the instances in the literature are <br> presented for group trip planning. Based on the preliminary <br> results, the solo trip seems to be better for smaller tourist <br> groups and less related tourist members, whereas the group <br> trip is preferred for larger groups that include tight relation <br> between group members.
