Many sellers wish to set a minimum cost for delivery below which they do not want to process orders. We need proper error codes and a defined flow for such cases.

**Article:** [Minimum-cost flow](https://cp-algorithms.com/graph/min_cost_flow.html)
**Problem:**
The proposed solution does not deal with negative cost cycles

**Describe the bug**
We think that we found an bug when trying to model a idle_heat_rate in combination with a unit_start_flow and unit_incremental_heat rate. Our hast three inflows: steam, raw_metha…

### Question
In Ebb-and-Flow there are two subprotocols providing availability and finality respectively which are then coupled.
When starting a "known attack case analysis" (such as in #39) and a…

## Problem Definition
What problem is this solving?
Currently, a user can submit transactions with zero fees or with insufficient fees or use an account that does not have enough balance to pay …

The network generation subproblem is infeasible:
- changing mcp of process stream H1 makes problem feasible again
- I suspect its the mass flow balance of the internal nodes of the superstructure t…

Maybe it's not as popular as some of the other graph algorithms, but it gets covered in Skiena's Algorithm Design Manual and is on my syllabus here at UD. So it'd be really great to have some OpenDSA …

Currently, there is nothing preventing simultaneous starts and shutdowns and if there are no start costs, this is seen. It's also used by the model to avoid the ramp_up/down_limit if start_up/shut_dow…
