About
In this project, we solve the NP-Complete Knapsack Problem using the metaheuristic Variable Neighborhood Descent (VND). To the control heuristic, we use Randomized Greedy.
How to run
To run this project, you need to do three things:
- Compile;
- Choose a test file, inside src/test-cases directory;
- Run the executable.
To make this process simpler, we created a Makefile. In this Makefile, he already have some ready bash commands:
- make compile: compile all cpp files in an executable named main
- make run: execute the main file with a chosen test case, this command were created to be a easy way to test different scenarios
- make runLow: execute the compiled project with a lower sized knapsack
- make runLarge: execute the compiled project with a larger sized knapsack
- make all: make compile + make run
- make allLow: make compile + make runLow
- make allLarge: make compile + make runLarge
Output
After running the project, it will print the results in the console.
It will print three things:
- Knapsack details;
- Randomized Greedy solution, profit and weight;
- VND solution, profit and weight.
