                         with an especial focus on the 1-Nearest Neighbor, and the 
                         Optimum-Path Forest supervised classifiers. The first was 
                         developed in the 1960s, while the second was recently proposed in 
                         the 2000s. Although, they were developed around 40 years apart, we 
                         can find many similarities between them, especially between 
                         1-Nearest Neighbor and Optimum-Path Forest. This work shows that 
                         the Optimum-Path Forest classifier is equivalent to the 1-Nearest 
                         Neighbor classifier when all training samples are used as 
                         prototypes. The decision boundaries generated by the classifiers 
                         are analysed and also some simulations results for both algorithms 
                         are presented to compare their performances in real and synthetic 
                         data.",
