// implementation('com.google.ortools:ortools-java:9.11.4210')
}package dev.claudio;
import com.google.ortools.Loader;
public class Main {
public static void main(String[] args) {
long start = System.currentTimeMillis();
System.out.println("Started");
Loader.loadNativeLibraries();
long timeMs = System.currentTimeMillis() - start;
System.out.printf("Time taken: %.3f seconds%n", timeMs / 1000.0);
}
}- On v9.12:
Time taken: 13.387 seconds - On v9.11:
