A few comments

• Time to run averages around 15 seconds on my M1 macbook pro. This should leave plenty of room on slower machines.
• There is still alot of fine tuning that can be done to increase performance.
• There is a lot of dead code that I didn't prune. I left it for visibility, so I can demonstrate my process as I worked through the problem.
• This is only my second project in go. So my understanding of the language was constantly evolving throughout this project. Leading to some inconsistencies.

Build and execute

This was built using go version 1.21.2

run go build . This will output an executable called vehicle-routing-problem

The executable takes a single argument for location of a problem file

example ./vehicle-routing-problem ./problems/problem1.txt

Visualizations

• Visualizations can increase runtime and should not be used when benchmarking the program runtime.
• Use the --driver-route-file to define a file location for driver schedules.
• Use --driver-count to define how many drivers per driver route file. Default will include all drivers in single file. If multiple files are required a suffix will be added to the file name.
• A file called annealing_graph.png and annealing_temp.png will be created, this cannot be changed at the moment.
