The research aims to develop an exact method for nesting problems that incorporate guillotine constraints.
Developed a branch-and-cut algorithm based on the dotted board model.
Identified non-guillotinable patterns through iterative elimination.
Utilized D-functions and cliques in incompatibility graphs for piece placements.
Adapted the approach to four different nesting problem variants.
The method achieved optimal solutions for most test instances.
Identified unsolved instances indicating areas for future research.
Unresolved problems highlighted the limitations of the model.
A challenge remains in extending the model to continuous domains.
