1.0. Download all .cpp and .h files.
2.0. Start a new C++ project and name it "DCNP". Add all .cpp files to "DCNP" Source files and all .h files to its Header.
3.0. Build the solution (CTRL+SHIFT+B).
4.0. Open Windows Command Prompt.
5.0. Find "Release" folder in the "DCNP" folder. Type " cd [folder address of "Release"] " and press Enter.
6.1. To see the results for "Recursive (R) formulation", type " DCNP.exe Recursive dimacs [folder address of the instance] \ [name of instance].graph [value of k] [value of b] " and press Enter.
6.2. To see the results for "Path-like formulation (PATH)" where k=3, type " DCNP.exe Path_like_k3 dimacs [folder address of the instance] \ [name of instance].graph [value of b] " and press Enter.
6.3. To see the results for "Path-like formulation (PATH)" where k=4, type " DCNP.exe Path_like_k4 dimacs [folder address of the instance] \ [name of instance].graph [value of b] " and press Enter.
6.4. To see the results for "Thin formulation (THIN_I)" using integer separation, type " DCNP.exe Thin_I dimacs [folder address of the instance] \ [name of instance].graph [value of k] [value of b] " and press Enter.
6.5. To see the results for "Thin formulation (THIN_F)" using fractional separation, type " DCNP.exe Thin_F dimacs [folder address of the instance] \ [name of instance].graph [value of k] [value of b] " and press Enter.
