psuedocode for my program using GA and PSO is it possible?

Step 1: select h value [2 4] with ga (how to write objective fn for this random selection of h vlaues during every iteration till we get optimized cost)

step 2: Select tau value [6 100] with ga (how to write objective fn for this random selection of tau vlaues)

step 3: select n value [3 4] with ga (how to write objective fn for this random selection of n vlaues)

step 4: select k value [0.25 3] with pso (how to write objective fn for this random selection of k vlaues)

step 5: vector x=[h tau n k]

step 6: calculate fitness value (cost function) save vector x (here any algorithm ga or pso can be used to optimize. i have objective function for this..)

step 7: goto step 1-step5 select new x vector and optimize the cost function
