public class JsonSolution
extends Object

This class represents the solution of a Linear Programming (LP) problem in JSON format. The generated JSON follows this structure:

 {

         // Information about the processing (duration, number of threads, etc.)
     },
     "objectiveType": "min",
     "status": "optimal",
     "solution": {
         "objectiveValue": 1244.0,
         "variables": {
             // Variable values
         }
     },
     "relaxedSolution": {
         "objectiveValue": 1244.0,
         "variables": {
             // Relaxed solution variable values
         }
     }
 }
