make an AI Flee

so im working on a game like agar.io, im making an AI that has 3 states (FindFood, Chase, Run) i have little pieces of food that spawn all over the map, and the AI will chase the closest pice of food. Then if a player comes in range, and has less mass than this AI, the AI will chase that player until it either eats it, or it gets out of range. Now i need to make "Run" which will be if a player with more mass comes into range, this player will run away. But the problem, is i need it to be able to run from multiple players at once, cus say that 2 players come in range with more mass, it can't just run in the opposite direction of bot, i would need it to run in-between them, but i don't know how to do this. here is my script

 public float timer;
 private float dist;
 private GameObject currentTarget;
 private GameObject enemy;
 private GameObject currentFood;
 public float Speed = 20f;
 public GameObject[] Targets;
 public GameObject[] Foodtarget;
 public Rigidbody rb;
 public Rigidbody otherRB;


 void Start()
 {
     rb = GetComponent<Rigidbody>();
 }
 void Update()
 {
     Targets = GameObject.FindGameObjectsWithTag("Player");
     Foodtarget = GameObject.FindGameObjectsWithTag("Food");
     timer += Time.deltaTime;


     {
         currentTarget = ChooseNewEnemy();
         currentFood = ChooseFood();
         StopAllCoroutines();

         if (currentTarget != null && rb.mass > otherRB.mass)
         {
             if (rb.mass > otherRB.mass)
             {
                 StartCoroutine(ChaseTarget(currentTarget));
             }
             Debug.Log("Player");
         }

         else if (currentFood != null)
         {
             StartCoroutine(ChaseFood(currentFood));
             Debug.Log("Food");
         }


     }

 }
