Heuristic improvement methods: How should starting solutions be chosen?

1980
A theoretical framework for improvement heuristic methods, as applied to discrete optimization problems, is put forward. The problem of choosing a suitable set of start points, from which to perform hill-climbs, is identified and some possible solutions considered. Numerical results are presented.

Recovering Indirect Solution Densities for Counting-Based Branching Heuristics

2011
Counting-based branching heuristics in CP have been very successful on a number of problems. Among the few remaining hurdles limiting their general applicability are the integration of counting information from auxiliary variables and the ability to handle combinatorial optimization problems.

Alignment characters, dynamic programming and heuristic solutions

1998
The method of direct optimization of nucleic acid sequences proposed by Wheeler (1996) is elaborated and explained in light of dynamic programming procedures. An exact solution to the problem of phylogenetic reconstruction of unequal-length sequences is described, and its impracticality demonstrated.

Optimal solutions versus ‘good’ solutions: An analysis of heuristic decision making

Omega, 1978
Abstract The portion of business problems which lend themselves to solution by existing optimization techniques are a minor subset of the business problems which can be defined and attacked by logical devices. Heuristics simplify the environment of the decision maker by permitting him to make decisions quickly without considering the innumerable ways
