Use this sheet to define solver-level configuration parameters.

Each row represents a configurable parameter and its associated value. These settings control how cuOpt solves the model but do not change the structure of the routing data itself.

Parameter names are predefined in the template and should not be modified. Each of the parameter values may be left as their defaults, in which cuOpt will use its default value.

Parameter

Specifies the solver parameter to configure. The following parameters are supported:

• Time limit

• Minimum vehicles

• Break method

Each parameter should only appear once.

Value

Specifies the numeric or categorical value associated with the parameter.

The interpretation of this value depends on the selected parameter (see below).

Time limit

Defines the amount of time cuOpt will spend solving the vehicle routing model model. It will continue trying to find improving solutions for this length of time. The value must be entered as a positive number and represents seconds.

If left blank, cuOpt uses its default time limit, which is: 10 + (number of tasks ÷ 6) seconds.

Minimum vehicles

Specifies the minimum number of vehicles that must be used in the solution.

The value must be a non-negative integer. If left blank, cuOpt may use any number of available vehicles.

Break method

This setting determines how break locations are defined. Both methods (uniform and non-uniform) define breaks using the same fields (Vehicle ID, break start window, break end window, and break duration). The difference is how allowable break locations are specified. With Uniform, all breaks share a single list of possible break locations defined in the Uniform Break Locations sheet. With Non-uniform, break locations can be defined separately for each break using the Non-uniform Break Locations sheet, allowing different breaks to have different sets of allowable locations.

The value for Break method should be either "Uniform" or "Non-uniform."

• If the Break method is set to Uniform, the model uses the Uniform Breaks and Uniform Break Locations sheets.

• If the Break method is set to Non-uniform, the model uses the Non-uniform Breaks and Non-uniform Break Locations sheets.

Rules and Structure

• Parameter names are predefined and should not be edited.

• Each parameter should appear only once.

• Values must match the expected format for the given parameter.

• Leaving a parameter value blank causes cuOpt to use its default behavior.
