Creating a number station Oleksandr R. It is more that I enjoy the sound, (and creep out the neighbours) :) |

How do I make Reduce yield all solutions explicitly? Allright, Thanks! This is the solution I went for, but it seems a bit hackish. So, I suspected that it might be possible to do it in a more natural way, but apparently not... |

How do I make Reduce yield all solutions explicitly? But what if I have more than one linear equation, and/or do not know if the equations are linear? |

How do we solve Eight Queens variation using primes? Then this is not aa n-queen problem, but an n-rook problem... |

How to use mathematica to create school time-table? Mathematica does not come with genetic algorithms as built-in functions. However, it is rather easy to implement yourself; You need a fitness function (that assigns a number that represents how good a schedule is), and a function for randomly mutate a schedule a bit (switching classes, rooms, etc). Then, start with 100 randomly generated schedules, select the top 10 based on their fitness, and create mutated copies of these until you have 100 again. Repeat until the best schedule is good enough. |

Finding a percolation path You can also do binary search on the r, reducing the complexity a bit more. |

Bug in Integrate for Mathematica Well, yes, but the same assumptions are made in both integrals. What surprises me is that factorization of the integrand changes the answer. |

Bug in Integrate for Mathematica Ah, but what are the assumptions in this case? I guess the inequalities forces the variables to be real, but the region one integrates over is also a real domain... |

Bug in Integrate for Mathematica Yes, I know that NIntegrate manages to get the answer correct. What I am curious about, is why the two identical integrals give different answers, depending on if the integrand is factorized or not. |
