Study Notes
Branch And Bound Optimization
- A method used to solve cutting stock problems
- Combines two techniques:
- Branching: divides the problem into smaller sub-problems
- Bounding: calculates a bound on the optimal solution for each sub-problem
- Two main types of bounding:
- Lower bounding: provides a lower bound on the optimal solution
- Upper bounding: provides an upper bound on the optimal solution
- Can be used to solve both one-dimensional and two-dimensional cutting stock problems
Dynamic Programming Applications
- A method used to solve complex problems by breaking them down into smaller sub-problems
- Applications in cutting stock problems:
- Solving one-dimensional cutting stock problems
- Solving two-dimensional cutting stock problems
- Key characteristics:
- Overlapping sub-problems: sub-problems may have some overlap
- Optimal substructure: the problem can be broken down into smaller sub-problems
Multistage Decision Making
- A method used to solve complex problems by breaking them down into multiple stages
- Applications in cutting stock problems:
- Solving problems with multiple stages of cutting and assembly
- Solving problems with multiple types of materials
- Key characteristics:
- Multiple stages: the problem is broken down into multiple stages
- Decision making: decisions are made at each stage to optimize the solution
Algorithmic Complexity Analysis
- Analysis of the computational complexity of algorithms
- Importance in cutting stock problems:
- Evaluating the efficiency of different algorithms
- Comparing the performance of different algorithms
- Key metrics:
- Time complexity: the computational time required to solve the problem
- Space complexity: the memory required to solve the problem
Optimization Problem Solving
- Cutting stock problems are a type of optimization problem
- Goal: find the optimal solution that minimizes or maximizes a objective function
- Key characteristics:
- Objective function: a function that measures the quality of the solution
- Constraints: limitations on the solution
- Optimization techniques used in cutting stock problems:
- Linear programming
- Integer programming
- Heuristics
