Attribute Index and Uniform Design Based Multiobjective Association Rule Mining with Evolutionary Algorithm

Pseudocode 3

Pseudocode of decoding.

decode(chrom): decode from chrom to generate the antecedent and the consequent.

Input: chrom indicates a chromosome.

Output: the antecedent and the consequent of an association rule.

 antecedent ← Φ;

 consequent ← Φ;

 for  the 𝑖th gene chrom(𝑖) ∈ chrom

  if  chrom(𝑖) = 1

   antecedent ← antecedent ∪  {𝑖};

  end if

  if  chrom(𝑖) = 2

   consequent ← antecedent ∪  {𝑖};

  end if

 end for

 return  antecedent, consequent;
