What I have tried:

#include<cmath>
#include<ctime>
#include<iomanip>
#include<string>
#include<vector>
using namespace std;
int main()
{
   vector<int> choosen_numbers;
   unsigned int i;
   int amount_of_numbers;
   int storage_memory;
   int minimum;
   int x;
   cout <<"How many numbers?";
   cout <<endl;
   cin >> amount_of_numbers;
   choosen_numbers.resize(amount_of_numbers);
   cout << "Please enter the numbers";
   storage_memory = 0;
   for (i = 0 ; i < choosen_numbers.size() ; ++i)
   {
      cin >> choosen_numbers.at(i);
      if (choosen_numbers.at(i) >= 0 || choosen_numbers.at(i) < 0)
      {
         storage_memory = i;
      }
   }
   minimum = choosen_numbers.at(0);
   for ( i = 0 ; i < amount_of_numbers ; ++i)
   {
      if(minimum > choosen_numbers.at(i))
      {
         minimum = choosen_numbers.at(i);
      }
   }
   cout <<"The smallest missing number is ";
   for ( i = 0 ; i <  amount_of_numbers ; ++i)
   {
      minimum = 1 + minimum;
      for (int j = 0 ; j < amount_of_numbers ; ++j)
      {
         if(minimum == choosen_numbers.at(j))
         {
            cout << choosen_numbers.at(j) + 1;
         }
      }
   }
   return 0 ;

What is your question?

You're setting your minimum incorrectly. I'd initialize it to INT_MAX. Then the test would become
    if ( choosen_numbers.at ( i ) < minimum )
      {
      minimum = choosen_numbers.at(i);
      }


FYI "choosen" should be spelled "chosen".
