Here are some things that may help you improve your code. Windows Vista Service Pack 3 Espanol Iso Mega. Don't abuse using namespace std Putting using namespace std at the top of every program is that you'd do well to avoid.

Rethink your object design Right now, the Solver object simply holds two dozen static strings. It has no intelligence and does not, in any sense, know anything about the cube it purports to solve. A better solver might keep a model of the scrambled cube to track its state. Don't optimize blindly First, we should keep in mind what Donald Knuth has said about optimization: 'The real problem is that programmers have spent far too much time worrying about efficiency in the wrong places and at the wrong times; premature optimization is the root of all evil (or at least most of it) in programming.' Your particular program probably spends 99% of its time doing I/O, so the performance differences among possible alternatives is probably best approximated as zero. If what you're really after is a better algorithm, then that's a different problem. Don't use std::endl if ' n' will do Using std::endl emits a n and flushes the stream.

Require 'rubiks_cube' cube = RubiksCube::Cube.new cube.solved? #=>true scramble = 'U D B2 U B D2 B2 F' R' U2 F U' L2 F L2 B2 L2 R' U R' U' D R2 F2 B2' cube.perform! Scramble cube.solved? #=>false solution = RubiksCube::TwoCycleSolution.new(cube) solution.length #=>458 puts solution.pretty # Setup: L2 # Fix:.

Unless you really need the stream flushed, you can potentially improve the performance of the code by simply emitting ' n' instead of using the potentially more computationally costly std::endl. Use string concatenation The code currently includes these lines: cout.
