Addition-subtraction chain
text:
An addition-subtraction chain, a generalization of addition chains to include subtraction, is a sequence a0, a1, a2, a3, ... that satisfies An addition-subtraction chain for n, of length L, is an addition-subtraction chain such that a L = n . That is, one can thereby compute n by L additions and/or subtractions. By definition, every addition chain is also an addition-subtraction chain, but not vice versa. Therefore, the length of the shortest addition-subtraction chain for n is bounded above by
