This paper describes a CAD system based on a sequential constraint-solver.
However, solution time is obtained efficiently by avoiding big numbers in the sequential constraints.
For each design solution, reconfiguration process to change from one machine configuration to another configuration is modeled by a generic process AND-OR graph that is composed of operation candidates, sequential constraints among operations and operation parameters.
"When a task cannot be partitioned because of sequential constraints, the application of more effort has no effect on the schedule.
Totally, 187 1H-1H distance constraints were obtained, including 101 intraresidue constraints, 45 sequential constraints and 29 medium constraints, 12 long range constraints.
Both of these sequences were equated along salient sequential constraints of simple frequency, first-order transition frequency, reversal frequency (e.g., 1-2-1), and rate of full coverage.
But before that we will describe the method to compute the optimal delineation given the matrix ℋ. Dynamic programming is perfectly suited when dealing with problems that contain sequential constraints, where the solutions to the subproblems have a recursive overlapping substructure (Bellman, 1957).
end{aligned}In contrast, the non-sequential constraints can be obtained from prior knowledge about the motion or observations with external sensors.
The first type is a sequential constraint (Rae, 1994) that simulates both crop sequences over time (e.g. second winter wheat follows a first cereal) and differences in the supply and demand of nutrients over time (e.g. first winter wheat following winter beans requires less nitrogen than second winter wheat as there is assumed to be a greater residual supply of nitrogen in the soil).
