Free solve script

GODLIKE (Global Optimum Determination by Linking and Interchanging Kindred Evaluators) offers you a powerful program which is a generation of various population-based global optimization schemes. Also, it handles both single- and multi-objective optimization, simply by adding additional objective functions.

Major Features:

1. GODLIKE solves optimization problems using relatively basic implementations of a genetic algorithm, differential evolution, particle swarm optimization and adaptive simulated annealing algorithms.
2. Its power comes from the fact that these different algorithms run simultaneously (linked), and members from each population are occasionally swapped (interchanged) to decrease the chances of convergence to a local minimizer.
3. It is primarily intended to increase ROBUSTNESS, not efficiency as it usually requires more function evaluations than any of the algorithms separately.
4. It's also intended to do away with the need to fine-tune these algorithms each and every time you encounter an optimization problem, AND to generalize optimization itself (it's both a single and multi-objective optimizer), AND to generate simple plots to be used in quick reports etc.

wavelength is a small yet useful script for everyone. It actually solves the dispersion relation for ocean surface waves using the Newton-Raphson method. It can also account for wave-current interaction by solving a modified form of the dispersion relation proposed by Jonsson (1970).

• T = Wave Period, (seconds)
• d = Water Depth, (m)
• U = Current Velocity, (m/s)
• delta = direction of current (rad) with respect to the cross-shore direction
• alpha = direction of waves (rad) with respect to the cross-shore direction
• tol = Maximum tolerance allowed for L, the default is 1e-6 (Generally 3 iterations)

Output:

• L = Wave length, (m)
• e = Relative error of L
• c = Iteratios
