I am working on my nsga2 problem about nsga-ii HOT 4 OPEN

hi. actually, I did not use your package. I working in my own code. I study some of your code because you work on general nsga2. My problem is more complex; If you can help me. I appreciate it. I have 10 decision variable with 5 attributes. I need to store them in my decision variable class. Do you think that hash table is okay ? I work with c#. for example I have x with x upper bound is 750 and lower bound is 200. x has Triangular distribution function with these parameters ('a',24,'b',380,'c',528); x has result at the end based of distribution function x = 320 also y upper bound is 650 and lower bound is 200. x has Normal distribution function with these parameters ('mu',330,'sigma', 96.6); y has result at the end based of distribution function x = 440 I need to send these x.result and y.result and the others to optimization problem class to evaluate the 10 chromosomes in Arena 14 simulation and gain 2 objective function which called customer backlogged time and whole cost of production. Did you get what I am talking about?? x = (key: x, upper _bound value:750, lower _bound value:200, Decision _Variable _Type value:Real, Distribution Function Type value:Triangular , inputs value:[ 24,380,528]) y = (key: y, upper _bound value:650, lower _bound value:200, Decision _Variable _Type value:Real, Distribution Function Type value: Normal , inputs value:[330, 96.6]) chromosome(1) ----> optimization problem[0] = (x=300, y=330 , .......) result of optimization objective function: (time= 6000 min, cost=3 m$) you did not develop this part because you do not have actual problem. thanks. I am looking forward to hearing from you. bahar saremi

1. What exactly is x and y? What do they represent in your problem? in real world, each chromosome can be static or dynamic. in my problem set, there are 10 chromosome. they are not static such as 20 or 1000, or so on. they produce from distribution function. Do you know about distribution function? such as normal ,... in my case each chromosome before produced should be called decision variable. each decision variable has different fields, as I explain it before. x is one of 10 decision variable. x ---> [200,750] distribution function : x~N(mu: 330, sigma: 96.6) each problem has their own type in operation research such as Real, integer, linear, ...... If you pass static or operation research; you can get what I am saying. nsga2 and other meta-heuristic algorithms are used to solved complex operation research problems. so I need to store each of decision variables before produced chromosome. x: decision variable one is the result of x~N(mu: 330, sigma: 96.6) = 340. for example, my chromosome set is [x1= 340, x2=400,x3=500,x4=440, x5=600, r1=900,r2=1100,r3=1020, r4= 1153,r5= 1200] I optimize the stochastic problem the whole cost production and the backlogged time of costumers of one automation company. they-chromosomes- are not static they are stochastic. I could not use your package because I am working on simulation optimization problem. In real world, If you study statistic you know each population has their own distribution function. *Did you get what I am talking about???🤔 * 2. Is each chromosome considered to be a solution to a different optimization problem? I do have 10 chromosomes with 2 results which are called objective functions in operation research. [x1= 340, x2=400,x3=500,x4=440, x5=600, r1=900,r2=1100,r3=1020, r4= 1153,r5= 1200] ---->[ Total cost = 351311521.6468 , wating Time= 4809.9083 s] I coded this problem with Matlab last year; I working to make it more efficient with c#. If i make you confused, I am sorry. I just ask you to help me to correct these 2 classes- decision variable class and optimization problem class- which you called chromosome. thanks. I am looking forward to hearing from you.
