Computational complexity and simulation of rar...
from pelikan, posted 3 years ago in Finance. 1404 views
We discuss the computational complexity of random 2D Ising spin glasses, which represent an interesting class of constraint satisfaction problems for black box optimization. Two extremal cases are considered: (1) the +/- J spin glass, and (...

The Bayesian Optimization Algorithm with Substr...
from pelikan, posted 3 years ago in Finance. 1647 views
This work studies the utility of using substructural neighborhoods for local search in the Bayesian optimization algorithm (BOA). The probabilistic model of BOA, which automatically identifies important problem substructures, is used to def...

Efficiency Enhancement of Probabilistic Model B...
from kknsastry, posted 3 years ago in Finance. 1556 views
This paper presents two different efficiency-enhancement techniques for probabilistic model building genetic algorithms. The first technique proposes the use of a mutation operator which performs local search in the sub-solution neighborh...

Sporadic Model Building for Efficiency Enhancem...
from kknsastry, posted 3 years ago in Finance. 1099 views
This paper describes and analyzes sporadic model building, which can be used to enhance the efficiency of the hierarchical Bayesian optimization algorithm (hBOA) and other estimation of distribution algorithms (EDAs). With sporadic model bu...

Hierarchical BOA on Random Decomposable Problems
from kknsastry, posted 3 years ago in Technology. 1217 views
The hierarchical Bayesian optimization algorithm (hBOA) can solve nearly decomposable and hierarchical problems scalably and reliably. This paper describes a class of random additively decomposable problems with and without interactions bet...
