How did Uncle Nowruz deliver the HaftSeen using Pyomo?

Uncle Nowruz is bringing new year's celebration to all Iranian, and many other nationalities in the middle east region (Afghanistan, Azerbaijan, India, Iraq, Kyrgyzstan, Kazakhstan, Pakistan, Tajikistan, Turkey, Turkmenistan and Uzbekistan). He has been doing the Nowruz (newday) tradition since 3000 years ago.

An important part of this tradition, Uncle Nowruz is about to distribute the elements of Haftseen (7Seens) to 405 big cities of Iran.

Haftseen is made of 7 elements as follows:

Sabzeh?(????): Sprouting /Grass: the symbol of rebirth and growth.

Samanu?(????): Samanu: the symbol of power and strength.

Senjed?(????): Elaeagnus angustifolia: the symbol of love.

Somāq?(????): Sumac: the symbol of sunrise.

Serkeh?(????): Vinegar: the symbol of patience.

Seeb?(???): Apple: the symbol of beauty.

Seer?(???): Garlic: the symbol of health and medicine.

The destinations of Uncle Nowruz are specified on Iran's map as follows:

He wants to start from Tehran (capital) and visit all the cities and return to the same point. He intends to deliver the Haftseen elements to all people so they can start the new year on Sunday March 20, 2022, 19:03:26 PM Tehran time.

So he decided to use Pyomo for solving the relevant TSP formulation.
