/src are two scripts that are similar to extract the desired dual values

### Gurobi
**please add here**
```
# %%
import gurobipy as gp
import pandas as pd

# read lp file
lp_file = gp.read("out/clews.lp")

# optimize
lp_file.optimize()

# dictionary over the dual values

# %%
# equations of interest EBb4 or EBa11 or E8
# key is the equation name
# val is the dual_value

eq = []
value = []
for key, val in dual_v.items():
if "EBb4" in key or "EBa11" in key or "E8" in key:
eq.append(key)
value.append(val)
# DataFrame Columns "Constrain" = equeation, "Dual_Value" = value
df = pd.DataFrame({'Constraint': eq, 'Dual_Value':value })


# %%
# write to csv
df.to_csv("dual_values.csv")
```
The csv looks like this:
```
Constraint Dual_Value
EBa11_EnergyBalanceEachTS5(RE1,S11,ADSL,2022) 2.81E-05
