`io_api="mps"` leads to memory overhead

1

Hi, I was looking into memory consumption a little, and it seems that that passing an LP to the solver (Gurobi in this case) using the .mps format has a...

Docstring of `Model.solve` defines return type as `Model`: https://github.com/PyPSA/linopy/blob/ecbc96266e3195b756fa528ff2faa4afe9243743/linopy/model.py#L996-L999 But a tuple of status and termination condition is returned in line 1085 and line 1111: https://github.com/PyPSA/linopy/blob/ecbc96266e3195b756fa528ff2faa4afe9243743/linopy/model.py#L1085 https://github.com/PyPSA/linopy/blob/ecbc96266e3195b756fa528ff2faa4afe9243743/linopy/model.py#L1111

Based on the discussion in #256, I started using `.loc[indices]` in arithmetic expressions and observed some inconsistencies (or I still do not understand the behaviour to 100% ^^) Following setup:...

Support constant values in objective

1. if the problem need to convert multi-objectives to singe-objective, it's necessary to make normalization involving some constant variables. It's not conveniet to construct objective containing constant, such as x+1...

Wish to add model.interrupt()/terminate() to api

In some cases, when solving a certain MIP problem, the solver may become slow. If the solver is called through an API request, it is not possible to directly stop...
