i am getting different results for different times of running the genetic algorithm

hi i'm working on a project in which i have to minimize the net annual cost( objective function). the variable range is in 500-5000. i am getting different results when i run it several times and also the results are weird. can anyone help me i have attached my objective function file and can anyone give me suggestions in choosing the parameters like mutation rate etc. thank you in advance

Genetic algorithms involve randomization. The results will only be the same if your function does not have wide local minimums and the calculation is run for long enough.
