% ------------------- Valid Range Of Algorithm -------------------
Start_points=[-4 -1.5];
End_points=[2 1];

%----------- Base Parameters Of Binary Gen Algorithm -------------

Gen_num=2;    % tedad moteghayer         
N=50;         % generation number 
Each_bits=[15 15];   % gen bit 
till=100;     %Number of regenaration   

%----------- Defination Temp Vars -------------
Max_reach=[];                   % Storing Best result (general best result)
Avg=[];             % Average Array of Fitness Function result for all generations
total_bit=sum(Each_bits);  % Total bits of each chrom 

%----------- Base Parameters Of Gen Algorithm -------------
Mutation_rate=0.05; 
Crossover_rate=0.4;  

%-------------------- Initializing First Generation --------------
Generation=round(rand(N,total_bit));

    Avg(it)=Avrg;
    Max_reach(it)=Max_fitness;
    Max_reach=sort(Max_reach);
    [Selected_gen]=Roulette(Generation,N,Selection_rate);           
    [Next_Gen]=Crossover(Selected_gen,Crossover_rate,N,total_bit);                                 
    [Generation]=Mutation(Next_Gen,Mutation_rate,N,total_bit);
