dynamic programming to solve resources allocation problem

dynamic programming for resource allocation problems

dynamic programming (dp) is a powerful algorithmic technique used for solving optimization problems by breaking them down into simpler subproblems. it is particularly useful for problems where the solution can be constructed from solutions to smaller subproblems. one common application of dynamic programming is in resource allocation problems, where we want to maximize or minimize some objective function while adhering to certain constraints.

understanding the resource allocation problem

in resource allocation problems, you typically have a set of resources to distribute among different tasks or projects to maximize profit or minimize costs. each task may require a certain amount of resources, and there may be limits on the total resources available.

let's consider a simple example: we have a fixed amount of resources (e.g., budget or time) and several projects, each with a specific resource requirement and a return on investment (profit). the goal is to choose which projects to fund in order to maximize total profit without exceeding the available resources.

problem formulation

1. **input:**
- a list of projects, where each project has:
- a resource requirement (cost)
- a profit (value)
- the total available resources (capacity).

2. **output:**
- the maximum profit achievable without exceeding the total resources.

example

imagine you have the following projects:

| project | resource requirement | profit |
|---------|---------------------|--------|
| a | 2 | 3 |
| b | 3 | 4 |
| c | 4 | 5 |
| d | 5 | 6 |

and let's assume the total available resources are 5.

dynamic programming approach

1. **state definition:**
let `dp[i][j]` be the maximum profit attainable using the first `i` projects with `j` resources.

2. **recurrence relation:**
- if we do not include th ...
