VRP or TSP with priortized pickup deliveries

[JohnMartin10000]

How can I add priority (ASAP and Normal) for some locations?

It seems that it is not possible for now with Python?

This is not an issue. Moving to discussions.

Did you try to use SetCumulVarSoftUpperBound() to incentive solver to visit ASAP node earlier ?

Lines 2494 to 2503 in b77bd3a

	/// Sets a soft upper bound to the cumul variable of a given variable index.
	/// If the value of the cumul variable is greater than the bound, a cost
	/// proportional to the difference between this value and the bound is added
	/// to the cost function of the model:
	/// cumulVar <= upper_bound -> cost = 0
	/// cumulVar > upper_bound -> cost = coefficient * (cumulVar - upper_bound)
	/// This is also handy to model tardiness costs when the dimension represents
	/// time.
	void SetCumulVarSoftUpperBound(int64 index, int64 upper_bound,
	int64 coefficient);
