The Thrift Savings Plan ( TSP) is a defined contribution plan for United States civil service employees and retirees as well as for members of the uniformed services. As of December 31, 2021, TSP has approximately 6.5 million participants (of which approximately 3.9 million are actively participating through payroll deductions), and more than ...
Solution of a travelling salesperson problem: the black line shows the shortest possible loop that connects every red dot. The travelling salesman problem, also known as the travelling salesperson problem (TSP), asks the following question: "Given a list of cities and the distances between each pair of cities, what is the shortest possible route that visits each city exactly once and returns ...
Combinatorial optimization is a subfield of mathematical optimization that consists of finding an optimal object from a finite set of objects, [1] where the set of feasible solutions is discrete or can be reduced to a discrete set. Typical combinatorial optimization problems are the travelling salesman problem ("TSP"), the minimum spanning tree ...
Low- and middle-income workers who aren't covered by a workplace retirement savings plan would get access to the federal Thrift Savings Plan, under a bipartisan bill introduced in the U.S. Senate ...
Thrift savings plans and 401(k)s are two types of retirement plans. We go over the characteristics of each type of plan. Retirement Basics: Thrift Savings vs. 401(k) Plans
Vehicle routing problem. The vehicle routing problem ( VRP) is a combinatorial optimization and integer programming problem which asks "What is the optimal set of routes for a fleet of vehicles to traverse in order to deliver to a given set of customers?" It generalises the travelling salesman problem (TSP).
Federal Employees Retirement System. The Federal Employees' Retirement System ( FERS) is the retirement system for employees within the United States civil service. FERS [1] became effective January 1, 1987, to replace the Civil Service Retirement System (CSRS) and to conform federal retirement plans in line with those in the private sector. [2]
Christofides algorithm. The Christofides algorithm or Christofides–Serdyukov algorithm is an algorithm for finding approximate solutions to the travelling salesman problem, on instances where the distances form a metric space (they are symmetric and obey the triangle inequality ). [1] It is an approximation algorithm that guarantees that its ...
