The phrase "are intractable for" is correct and usable in written English.
It can be used when discussing problems or issues that are difficult or impossible to manage or solve in relation to a specific subject or context.
Example: "The challenges we face in climate change are intractable for many policymakers, leading to a sense of helplessness."
Alternatives: "are unmanageable for" or "are insurmountable for".
On the other hand, these games are intractable; for example, partial-information games with simple reachability objectives are 2EXPTIME-complete.
There exist, however, problems that are intractable for resolution, for which clause-learning solvers are hence doomed.
Problem formulations are typically mixed or pure integer non-linear optimization models that are intractable for exact solution - in particular when empirically supported consumer choice models are incorporated.
The 6 DOF model for tanker is tactfully transformed into several strict-feedback nonlinear forms, especially the dynamics of the translational kinematics which are originally non-affine nonlinear forms and are intractable for controller design.
The 6 DOF model for aircraft is written into several strict-feedback nonlinear forms through tactful transformation, considering that the path dynamics are originally non-affine nonlinear forms and are intractable for controller design.
It has been shown in [36] and [37] that problems of this form are intractable for large numbers of small cells and UEs, i.g., the existence of a unique optimal solution is not guaranteed.
In these cases, the problem becomes an NP-complete combinatorial optimization problem, which is intractable for discrete optimization methods.
Stochastic dynamic programming is used to find the optimal schedule of resource allocation for small problems but is intractable for large problems owing to the "curse of dimensionality 8.
At the foot of the main escarpment, on the Sula Mountain plateau, and elsewhere an iron-rich laterite crust forms a surface that is intractable for agricultural production.
Each planner quickly solved problems whose subgoals were independent or trivially serializable, but problems with laboriously serializable or nonserializable subgoals were intractable for all planners.
