Hello everyone, I have encountered a perplexing problem when setting initial values using Gurobi. For example, if I want to set the initial value of a variable "var" to -10000.
And I manually checked that this initial value satisfies the constraints. However, Gurobi also reported during runtime that it successfully used the initial value I provided to solve the model: "User MIP start produced solution with objective 0 (0.02s) Loaded user MIP start with objective 0".
However, when I checked the values of the output variables that Gurobi successfully solved again, I found that the value had changed and was no longer -10000 that I provided, but became 0. However, when I checked the start property of the variable, it was still -10000, which confused me a lot. Can you help me with this?
