Global Scalable Optimisation

Scalability of systems performance becomes a challenge for modern digital systems. Achievement of system ability to complete wide range of tasks in terms of computational performance and effective use of resources require substantial research. Significant efforts are directed towards design of large scale hardware systems. However resolving scalable tasks require also scalable software.
The aim of this Competition is to highlight the results achieved by various methods on two global optimisation test for wide range of dimensions.

Test functions

Keane's Bump Test Function

Keane's Bump Test Function is hard constrained global optimisation problem. For this completion it is transformed for maximization.


where xi are the variables (expressed in radians) and n is the number of dimensions. Optimal values for variety of dimensions of this test are unknown.

Submission for Test 1

For details please see


Michalewicz Test function

Michalewicz test function is global optimisation problem. For this completion it is transformed for maximization.

The maximum is dependent on dimensions number and for variety of dimensions is unknown.
