Table 1:
Explanation of symbols used to describe algorithms in this paper. Note that the term memotype is used analogously to genotype as a specific set of allele values that may have several copies in a meme population. Note also that the sets of fitness improvement include all the steps taken during a local search.
SymbolAlgorithm described
Pmm Locuswise probability of mutating condition and action parts of meme rules. 
Pmg Componentwise probability of applying mutation to other elements of a meme. 
RL Maximum length of rule in memes. 
Xl Extreme-local strategy. Uses maximum observed fitness improvement when applying an individual meme, that is, sampled locally in solution space. 
Xg Extreme-global strategy. Uses maximum observed fitness improvement from all applications of a memotype, that is, sampled globally across solution space. 
Ml Mean-local strategy. Uses average observed fitness improvement when applying an individual meme, that is, sampled locally in solution space. 
Mg Mean-global strategy. Uses mean observed fitness improvement from all applications of a memotype, that is, sampled globally across solution space.
