Knapsack Solver

This is a simple Rust project for solving the 0/1 Knapsack problem.

Problem Description

The 0/1 Knapsack problem is a classic optimization problem where the goal is to select a subset of items, each with a weight and a value, to maximize the total value while staying within a given weight capacity.

Features

  • Iterator for generating all possible combinations of items.
  • Selection of the most profitable knapsack based on monetary value.

Installation

For Linux

Red Hat based distributions

  1. Download the latest rpm file from the release page, e.g.
wget https://github.com/vasigorc/Knapsack-Solver/releases/download/v0.0.1/knapsack_problem-0.0.1-1.x86_64.rpm
  1. Install the file
sudo rpm -i knapsack_problem-0.0.1-1.x86_64.rpm
# test installation
which /usr/bin/knapsack_problem
# returns /usr/bin/knapsack_problem

Runbook

# get help page
/usr/bin/knapsack_problem cli -h
Usage: knapsack_problem cli --clocks-file <FILE> --weight <FLOAT>

Options:
      --clocks-file <FILE>
  -w, --weight <FLOAT>
  -h, --help                Print help

# run the binary
/usr/bin/knapsack_problem cli --clocks-file sample_clocks.json -w 5.0
The best Knapsack combination for the provided input is Knapsack { contents: [Clock { weight: 2.0, price: 5.0 }, Clock { weight: 3.0, price: 8.0 }], capacity: 5 }

Development

GitHub Action Local Testing

This repository includes a script (run-gh-act.sh) that facilitates local testing of GitHub Actions workflows using the act tool. The purpose of this script is to simulate GitHub Actions locally before pushing changes to the remote repository.

Docker image

The Docker image used in the simulation is based on the buildpack-deps:22.04 image. It includes essential development tools and libraries, making it suitable for building and testing various software projects.

Prerequisites

  • Docker installed on your local machine
  • GitHub CLI (gh) installed
  • The act tool installed (Install using: gh extension install https://github.com/nektos/gh-act)

Usage

To run the local GitHub Actions workflow simulation, use the provided script:

./run-gh-act.sh
