Description: Generalized p-Mean Models
        ================================
        
        Collection of Generalized *p*-Mean Models (GPMM) with classic, fuzzy and un-weighted approach. This set of outranking methods are based on the concept of `weighted generalized p-mean <https://en.wikipedia.org/wiki/Generalized_mean>`_ of a sequence:
        
        In this project, we have included four different approaches:
        
        1. **Classic (WMM)**: The *M* score is computed per each alternative to generate a cardinal ranking.
        2. **Fuzzy (FWMM)**: The decision matrix is trapezoidal fuzzy shaped as *(x_L, x_1, x_2, x_R)* with LR-representation. Then, it is satisfied that *x_L <= x_1 <= x_2 <= x_R* per each component of the matrix.
        3. **Un-Weighted (UWMM)**: The weighting scheme is variable and it has attached a lower and upper bound per each component. As a result, it returns an interval *[M_L, M_U]*.
        4. **Fuzzy Un-Weighted (FUWMM)**: It combines both approaches in the decision matrix and the weighting scheme.
        
        
        Installation
        ======================
        
        You can install the GPMM library from GitHub::
        
        .. code:: sh
        
            git clone https://github.com/Aaron-AALG/GPMM.git
            python3 -m pip install -e GPMM
        
        
        You can also install it directly from PyPI::
        
        .. code:: sh
        
            pip install GPMM
        
        
        Example
        ======================
        
        GPMM is implemented in order to manage **Pandas** DataFrames as input data which will be converted to **NumPy** arrays. Here is an example in which we only use three alternatives and four criteria.
        
        
        Optimization in Python
        ======================
        
        This library uses the `minimize <https://docs.scipy.org/doc/scipy/reference/generated/scipy.optimize.minimize.html>`_ function of the scipy.optimize module to carry out the optimization problems. In particular, *M_L* and *M_U* are obtained one by one, thus we can apply the **SLSQP** method.
