Try routeXL I'm not sure how many nodes you can max out on though.
Here's an example of a 12 city output
- To add destinations, find them in the search bar and press enter. click on the
Address
drop down to change/modify the addresses you just added
- Click on
find route
for it to compute it
HEre's a screenshot of a run I did:

ODL Studio is an open source desktop application for planning vehicle routes - so it will solve your problem. It's free and we have people using it in many different countries throughout the world. Download from here http://www.opendoorlogistics.com/ or watch the tutorial video here https://www.youtube.com/watch?v=0DJdubVWX_A
It takes an Excel as input data which will help you. You can play around with the cost-per-km and cost-per-hour to have it automatically optimise for most efficient by time or mileage (given the size of your problem it will probably find the most optimal solution as well).
There is the personal route-planning software portatour which supports multiple stops and Excel upload.
- Sign up for an account and upload your excel. Pressing "update schedule" will give you the shortest route.
- portatour is made for sales reps visiting up to 1000 addresses repeatedly, so it has many more features which are specific for field sales, consulting, and maintenance. For example, opening times or visit intervals.
- The result route can be exported as iCal calendar.
- There is a free trial
Here is a screenshot of a generated Route on an iPad:

Check out Optimo Route - there is a free trial you can use. Import multiple addresses from MS Excel and easily plan optimal routes. You can also set things like service time (time you will spend at the location) and time windows (specific times you need to be at the location).
Routes can be exported to a GPS device (Garmin, Navigon, TomTom) or MS Excel.

Also take a look at Speedy Route - another optimal route planner website. You can bulk upload addresses, and then either print out the optimal route, or export the results to Excel via CSV.
Finding the most efficient route from a list of addresses sounds a lot like the Traveling Salesman Problem, one of the most studied problems in computer science. It's one thing to calculate a straight line distance but adding street routes makes this highly unlikely that you'll find an optimal distance.
I might have answered part of your problem on another page. This may not be useful but I'll include it anyway.

For Python, there are very few option for free source RS based image segmentation. I'll suggest two,
If it's not remote sensing I'll suggest OpenCV.
