Simulation of segments shared identical-by-descent (IBD) by
    pedigree members. Using sex specific recombination rates along the
    human genome (Halldorsson et al. (2019)
    <doi:10.1126/science.aau1043>), phased chromosomes are simulated for
    all pedigree members. Applications include calculation of realised
    relatedness coefficients and IBD segment distributions. 'ibdsim2' is
    part of the 'pedsuite' collection of packages for pedigree analysis.
    A detailed presentation of the 'ped suite', including a separate
    chapter on 'ibdsim2', is available in the book 'Pedigree analysis in
    R' (Vigeland, 2021, ISBN:9780128244302). A 'Shiny' app for visualising
    and comparing IBD distributions is available at
    <https://magnusdv.shinyapps.io/ibdsim2-shiny/>.

Some basic functions to implement belief functions including:
    transformation between belief functions using the method introduced by
    Philippe Smets <arXiv:1304.1122>, evidence combination, evidence
    discounting, decision-making, and constructing masses. Currently, thirteen
    combination rules and six decision rules are supported. It can also be
    used to generate different types of random masses when working on belief
    combination and conflict management.

The initial basic feasible solution (IBFS) is a significant step to achieve the minimal total cost (optimal solution) of the transportation problem. However, the existing methods of IBFS do not always provide a good feasible solution which can reduce the number of iterations to find the optimal solution. This initial basic feasible solution can be obtained by using any of the following methods. 
             a) North West Corner Method. 
             b) Least Cost Method. 
             c) Row Minimum Method. 
             d) Column Minimum Method. 
             e) Vogel's Approximation Method.
             etc.
