original: this has the advantage of evenly distributed spatial resolution without singularities -lrb- i.e. the poles -rrb- at the expense of somewhat greater numerical difficulty .
simplifications: this has the advantage of evenly distributed spatial resolution without singularities -lrb- i.e. the poles -rrb- at the expense of somewhat greater numerical difficulty this has the advantage of evenly distributed spatial resolution without singularities -lrb- i.e. the poles -rrb- at the expense of somewhat greater numerical difficulty . this has the advantage of evenly distributed spatial resolution without singularities -lrb- i.e. the poles -rrb- at the expense of rather bigger numerical difficulty . this has the upside of evenly spaced spatial resolution without singularities -lrb- i.e. the poles -rrb- at the expense of somewhat greater numerical problems . the advantage of evenly distributed spatial resolution withou singularities -lrb- i.e.the poles -rrb- is achieved at the expense of greater numerical difficulty this has the benefit of evenly spread out spatial resolution without singularities -lrb- i.e. the poles -rrb- at the expense of somewhat greater numerical difficulty . this has the advantage of evenly distributed spatial resolution without singularities at the expense of somewhat greater numerical difficulty . this has the advantage of evenly spreading out spacing without singularities -lrb- i.e. the poles -rrb- but with more difficulty with numbers .
