simplex-library

Biblioteca Node.js para resolver problemas de programacao linear com o metodo Simplex.

Instalacao

npm install simplex-library

Uso rapido

const { solveSimplexFromInput, makeZeroStringArray } = require('simplex-library');

const variableCount = 2;

const input = {
    objectiveType: 'max',
    objectiveMode: 'simplified',
    objectiveCoeffs: ['3', '5'],
    objectiveFormula: '',
    variableDomains: ['nonnegative', 'nonnegative'],
    constraints: [
        { coeffs: ['2', '1'], relation: '<=', value: '8' },
        { coeffs: ['1', '2'], relation: '<=', value: '8' },
    ],
};

const response = solveSimplexFromInput(input);

if (response.formError) {
    console.error('Erro de formulario:', response.formError);
} else if (response.result?.status === 'optimal') {
    console.log('Valor objetivo:', response.result.objectiveValue);
    console.log('Solucao:', response.result.solution);
}

console.log(makeZeroStringArray(variableCount));

API

solveSimplexFromInput(input): resolve o modelo e retorna { formError, modelWarning, result }.
makeZeroStringArray(size): cria um array de strings com zero, util para montar formularios.
