In Algorithms 3.1 and 3.2, there still exists difficulty to implement the projections P C and P Q with respect to the defined norms, especially when C and Q are general closed convex sets.
Finding a high accurate and efficient numerical method has become a significant research due to except for a few number of these equations, there exists difficulty to find the exact solution of fractional differential equations (FDEs).
However there exist some difficulties.
But there still exist great difficulties in constructing an accurate scale model including nonmetallic materials such as magnetic absorbing coatings.
The hybrid flow shop scheduling with multiprocessor task (HFSMT) problem is a substantial production scheduling problem for minimizing the makespan, and there exist many difficulties in solving large scale HFSMT problems which include many jobs, machines and tasks.
"But," he said, "I prefer an imperfect agreement that is living than a perfect agreement that doesn't exist". The difficulties far exceeded those surrounding other environmental treaties, experts said, because the treaty, by controlling carbon dioxide, the main greenhouse gas, would limit something released by almost every act of modern daily living.
Different from one-dimensional Hamiltonian systems, there exist two difficulties in higher-dimensional beam equations.
