new ([name=nil], cols, rows[, maximize=false])	Opens a new linopt.
size (lp)	Adds columns to the linear program.
add_cols (lp, cols)	Adds columns to the linear program.
add_rows (lp, rows)	Adds rows to the linear program.
set_col (lp, index, name, coefficient[, kind="real"[, lb=nil[, ub=nil]]])	Adds an optimization column.
set_row (lp, index, name[, lb=nil[, ub=nil]])	Adds an optimization row.
load_matrix (lp, row_indices, col_indices, coefficients)	Loads the entire matrix for the linear program.
solve (lp)	Solves the linear optimization problem.
read_problem (fname[, glpk_format=false[, maximize=false]])	Reads an optimization problem from a file for debugging purposes.
write_problem (lp, fname[, glpk_format=false])	Writes an optimization problem to a file for debugging purposes.

Functions

__gc (linopt)

Frees a linopt.

Parameters:

• linopt Optim Optim to free.

__eq (d1, d2)

Compares two linopts to see if they are the same.

Parameters:

• d1 Optim Optim 1 to compare.
• d2 Optim Optim 2 to compare.

Returns:

boolean true if both linopts are the same.

new ([name=nil], cols, rows[, maximize=false])

Opens a new linopt.

Parameters:

• name string Name of the optimization program. (default nil)
• cols number Number of columns in the optimization program.
• rows number Number of rows in the optimization program.
• maximize boolean Whether to maximize (rather than minimize) the function. (default false)

Returns:

Optim New linopt object.

size (lp)

Adds columns to the linear program.

Parameters:

• lp LinOpt Linear program to modify.

Returns:

1. number Number of columns in the linear program.
2. number Number of rows in the linear program.

add_cols (lp, cols)

Adds columns to the linear program.

Parameters:

• lp LinOpt Linear program to modify.
• cols number Number of columns to add.

add_rows (lp, rows)

Adds rows to the linear program.

Parameters:

• lp LinOpt Linear program to modify.
• rows number Number of rows to add.

set_col (lp, index, name, coefficient[, kind="real"[, lb=nil[, ub=nil]]])

Adds an optimization column.

Parameters:

• lp LinOpt Linear program to modify.
• index number Index of the column to set.
• name string Name of the column being added.
• coefficient number Coefficient of the objective function being added.
• kind string Kind of the column being added. Can be either "real", "integer", or "binary". (default "real")
• lb number Lower bound of the column. (default nil)
• ub number Upper bound of the column. (default nil)

set_row (lp, index, name[, lb=nil[, ub=nil]])

Adds an optimization row.

Parameters:

• lp LinOpt Linear program to modify.
• index number Index of the row to set.
• name string Name of the row being added.
• lb number Lower bound of the row. (default nil)
• ub number Upper bound of the row. (default nil)

load_matrix (lp, row_indices, col_indices, coefficients)

Loads the entire matrix for the linear program.

Parameters:

• lp LinOpt Linear program to modify.
• row_indices number Indices of the rows.
• col_indices number Indices of the columns.
• coefficients number Values of the coefficients.

solve (lp)

Solves the linear optimization problem.

Parameters:

• lp LinOpt Linear program to modify.

Returns:

1. number The value of the primal funcation.
2. table Table of column values.

read_problem (fname[, glpk_format=false[, maximize=false]])

Reads an optimization problem from a file for debugging purposes.

Parameters:

• fname string Path to the file.
• glpk_format boolean Whether the program is in GLPK format instead of MPS format. (default false)
• maximize boolean Whether to maximize (rather than minimize) the function. (default false)

Returns:

LinOpt Linear program in the file.

write_problem (lp, fname[, glpk_format=false])

Writes an optimization problem to a file for debugging purposes.

Parameters:

• lp LinOpt Linear program to write.
• fname string Path to write the program to.
• glpk_format boolean Whether to write the program in GLPK format instead of MPS format. (default false)
