    Simulated Annealing Algorithm in Excel

    I am trying to create the Simulated Annealing algorithm in excel to maximise: f(x) = x3-39x2 +144x-100 Subject to the condition 0≤x≤31 (iteration number n=50 and the temperature setting is T0=10, Tn=0.99*Tn-1). Using a normally distributed neighbourhood N(0, 12) with initial value from N(15...

    Calculate risk of death in a computer simulated world

    Hi all This is my first post here, so hello. I have a very difficult math problem, that I hope someone can help with. I am a programmer and I am interested in evolution, so I decided to create a computer simulated world. It is a very simple world with only a few functions at the moment. You...

    simulated negative binomial

    A sample of bay anchovy larvae counts yielded the data 158, 143, 106, 57, 97, 80, 109, 109, 350, 224, 109, 214, 84 The negative binomial(r,p) distribution (with mean m= r(1-p)/p and variance m + (m^2)/r ) is a reasonable model. For m=xbar, what values of r lead to simulated distributions...

    Simulated gravity due to acceleration

    I just need to have my working for the following question confirmed: "An 81 kg astronaut is launched into space on a Saturn rocket. The upward acceleration of a Saturn rocket shortly after blastoff is 80m/s^2. When the rocket is accelerating, what is the apparent weight of the astronaut, that...
