    Gift Finder

    Gift Finder

    Navegação em árvore binária baseada em perguntas e respostas

    O GiftFinder foi criado inicialmente pois muitas vezes ficamos em dúvida do que dar de presente para um amigo(a) ou parente. O aplicativo GiftFinder foi construído com um propósito puramente educacional, de forma a demonstrar, por meio de um algoritmo programado em Java, a navegação entre nós de uma árvore binária que foi estaticamente construída. O GiftFinder possui um comportamento similar ao Akinator, ou seja, dada uma resposta para uma pergunta, o algoritmo irá avaliar a resposta, tomar uma decisão, navegar entre os nós da árvore binária e sugerir opções de presentes. Se o último nó da árvore for alcançado o aplicativo exibe uma última sugestão de presente mesmo que a resposta for "Não". Esse comportamento foi propositalmente adotado para caso o usuário mude de ideia. Obs: Diferente do Akinator, o GiftFinder não possui inteligência artificial, ou seja, ele não é retro alimentado de informações para a criação de ramificações e nós.
