...Although mixedinteger linearing programming (MILP) based algorithms has been developed for parallel optimization of FIR filters with signed power of two coefficients [20], the programming and the partitioning of the problems are complicated, and therefore, no attempts have been made for the design of the filters sharing add-shift network among coefficients....

...It should be noted that the computer time required by running MILP is several orders of magnitude [29] of that required by other suboptimum techniques if only one processor is used; running MILP on parallel machines still requires more computer time than running other techniques on a single…...

...Mixed-integer linear programming (MILP) is the only known method that can provide the global optimum solution to the design of FIR filters with SPT coefficient values [2], [4], [27], although other computationally very much less demanding technique exist [29]....
