New technological tools emerge in a continuous and rising frequency, inserting them in the educational context and making optimal use of their resources is the role of the school and its actors. This research presents the results of a study that investigates the development and use of Augmented Reality in mobile applications in Basic Education Mathematics classes. To this end, an application was developed on the Android platform that allows the approach of the theme: regular solids, also known as Plato solids. The survey was conducted through a questionnaire used by a group of math teachers and undergraduate students of a full degree course in mathematics revealing that few had contact with this type of application, and also indicates that to combine mobile devices augmented reality resources denotes being relevant for approaching geometric solids.","PeriodicalId":30414,"journal":{"name":"Colloquium Exactarum","volume":"17 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84583909","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper was presented a maximum time-constrained vehicle routing problem, which identifying and implementing in C/C++ an algorithm that uses mathematic programming, heuristic and metaheuristic techniques. The adopted method obtains a solution that reduces eight to six steps performed by the company.
