I mostly wanted to emphasize how much better the improved formula from Wikipedia is (thanks for the pointer), while being barely more computationally costly than the classical Haversine formula: it seems one should always use the improved formula, rather than Haversine. A fórmula de haversine permite que o haversine de Θ (ou seja, o hav (Θ)) seja calculado direto pela latitude e longitude dos dois pontos: λ1, λ2 são a longitude do ponto 1 e longitude do ponto 2 (em radianos). Why does the change in heuristics cause it to be more accurate, and take longer to run? The first heuristic, distance squared, overestimates the real distance (by a lot, depending on the situation) even though the actual distance is computed the same way, because the actual distance is computed as the sum of single steps (the sum of squares. distances = haversine (cyc_pos.
